add more warning flags, correct syntax, add UNUSED macro, […]

- added -Wall -Wextra -pedantic to the compile options
- various syntax has been corrected:
  - static is used before const
  - correct integer types are used in for loops
  - empty newlines are added
- every command has an argc and argv but some don't use them so they are marked as potentially unused if compiled on a GNUC compatible compiler
- mark JSONC variables as advanced so they do not show up as generic variables
