added editorconfig plugin (#163)

* properly ignore comments on declarations
* strip newlines when insert_final_newline set to false
* force match up to the end
* support unset property
* make property values case insensitive
* handle indent_size when set to tab
* handle escaped comment chars
* also lowercase property names
* support utf-8 as on spec
* apply rules to unsaved unamed/named docs
* annotation fix
* added test suite and fixes for 100% pass rate
* do not force match from start, breaks 2 tests
* allow starting wild cards to match everything
* disabled print buffering
* make last line visible if insert_final_newline true
* use log_quiet for debug
* adapted to changes on lite-xl/lite-xl#1232
* properly return from add/remove_project_directory overrides
* Use new trimwhitespace functionality if possible
