Chat Filter using Flag Enums. (#270)

* Backing up local repo before upgrading OS, minor work on chat UI

* Cleaned out unnecessary modded files

* Got a working version of filter toggles based on flag enums

* Added localization to chatbox buttons

* Should actually fix modified proj files, thanks PJB

* Fixed enum operators to unset instead of toggle

* Added a local client class for storing net message details

* Reworked RepopulateChat to pull from a StoredChatMessage list

* Fixed messages dissapearing

* Re-ordered logic to be a bit more efficient with re-drawing chat
