Bracket Colors: Support user defined colors (#5)

* simple UI * start hooking up signals * mechanism to save settings from a conf file * save load settings for defaults button * less globals * better config color name * hook up colors * glib types * use colors from plugin config * update colors when settings change * reorganze, try to avoid giant files * update document colors when they switch * update headers * fix bug when some brackets werent getting added to bracket map * fix bug that was deleting newly inserted brackets * std::map insert doesnt overwrite, use insert_or_assign * handle when removing a bracket completes another * handle invalid color specs in config file * avoid static initialization fiasco * if there are problems loading config, use defaults * cleanup headers * mark GUI labels as translatable --------- Co-authored-by: Asif Amin <[email protected]>
