big refactor (#171)v1.10.0-rc1
* use in-file macros rather than global funcs for registering dll load callbacks
* move more things to macros
* fix debug crashes
* move sqvm funcs to sq managers
* get rid of context file
* refactor some squirrel stuff and ingame compilation error message
* move tier0 and playlist funcs to namespaces
* uiscript_reset concommand: don't loop forever if compilation fails
* improve showing console for ui script compile errors
* standardise concommand func naming in c++
* use lambdas for dll load callbacks so intellisense shits itself less
* use cvar change callbacks for unescaping ns_server_name and ns_server_desc
* add proper helpstrings to masterserver cvars
* add cvar help and find
* allow parsing of convar flags from string
* normalise mod fs paths to be lowercase
* move hoststate to its own file and add host_init hooks
* better IsFlagSet def
* replace files in ReadFromCache
* rename g_ModManager to g_pModManager

* add proper map autocompletes and maps command
* formatting changes
* separate gameutils into multiple r2 headers
* Update keyvalues.cpp
* move sqvm funcs into wrappers in the manager class
* remove unnecessary header files
* lots of cleanup and starting moving to new hooking macros
* update more stuff to new hook macros
* rename project folder (:tf: commit log)
* fix up postbuild commands to use relative dir
* almost fully replaced hooking lib
* completely remove old hooking
* add nsprefix because i forgot to include it
* move exploit prevention and limits code out of serverauthentication, and have actual defs for CBasePlayer
* use modular ServerPresence system for registering servers
* add new memory lib
* accidentally pushed broke code oops
* lots of stuff idk
* implement some more prs
* improve rpakfilesystem
* fix line endings on vcxproj
* Revert "fix line endings on vcxproj"
This reverts commit 4ff7d022d2602c2dba37beba8b8df735cf5cd7d9.

* Add some changes from main to refactor (#243)
* Add PR template
* Update CI folder location
* Delete startup args txt files
* Fix line endings (hopefully) (#244)
* Fix line endings (hopefully)
* Fix more line endings
* Update refactor (#250)
* Add PR template
* Update CI folder location
* Delete startup args txt files
* Add editorconfig file (#246)
* Add editorconfig file
It's a cross-editor compatible config file that defines certain editor
behaviour (e.g. adding/removing newline at end of file)
It is supported by major editors like Visual Studio (Code) and by
version control providers like GitHub.
Should end the constant adding/removing of final newline in PRs
* More settings
- unicode by default
- trim newlines
- use tabs for indentation (ugh)
* Ignore folder rename (#245)
* Hot reload banlist on player join (#233)
* added banlist hotreload
* fix formatting
* didnt append, cleared whole file oopsie
* unfuckedunban not rewriting file
* fixed not checking for new line

* Refactor cleanup (#256)
* Fix indentation
* Fix path in clang-format command in readme
* Refactor cleanup (some formatting fixes) (#257)
* Fix some formatting
* More formatting fixes
* add scriptdatatable.cpp rewrite
* Some formatting fixes (#260)
* More formatting stuff (#261)
* various formatting changes and fixes
* Fix changed icon (#264)
* clang format, fix issues with server registration and rpak loading
* fix more formatting
* update postbuild step
* set launcher directory and error on fail creating log files
* change some stuff in exploitfixes
* only unrestrict dev commands when commandline flag is present
* fix issues with cvar flag commit
* fixup command flags better and reformat
* bring up to date with main
* fixup formatting
* improve cvar flag fixup and remove temp thing from findflags
* set serverfilter better
* avoid ptr decay when setting auth token
* add more entity functions
* Fix the MS server registration issues. (#285)
* Port ms presence reporter to std::async
* Fix crash due to std::optional being assigned nullptr.
* Fix formatting.
* Wait 20 seconds if MS returns DUPLICATE_SERVER.
* Change PERSISTENCE_MAX_SIZE to fix player authentication (#287)
The size check added in the refactor was incorrect:
- 56306: expected pdata size based on the pdef
- 512: allowance for trailing junk (r2 adds 137 bytes of trailing junk)
- 100: for some wiggle room

* change miscserverscript to use actual entity arguments rather than
player index jank
* Fix token clearing hook (#290)
A certain someone forgot to put an `0x` in front of their hex number, meaning the offset is wrong.
This would cause token to be leaked again
