roomslist: reimplement filters implementation details: YO DAWG, I herd you like QSortFilterProxyModels, so I put a QSortFilterProxyModel in your QSortFilterProxyModel in your QSortFilterProxyModel in your QSortFilterProxyModel so that you can filter while you filter while you filter while you filter!

remove IFDEF 0 for sake of poor parser

room list: replace magic table column indexes with enum. makes future changes to the room list format way easier.

marked a couple of functions as inline resolved all warnings/hints/notes added -Ooregvar optimisation (stores frequently used variables in registers, saving ~30k code size)

make search filter field have a useable size on low frontend resolution

change every return value into a more pascal-ish form, using the name of the fucntion (helps the parser and macpas compaitilibity)

make column sorting three-state: asc -> dsc -> off/default (= by room state)

sort by room state by default

allow custom sorting of roomslist (by clicking on header sections)

add support for default pascal mode by removing default arguments value (maybe this also helps the parser)

Removing maps can cause desyncs. This is why we still have Cheese, Sticks, Sheep etc. They need to remain until replacements are put in place.

remove map: Sticks reason: obvious :P

roomslistmodel: prettier names for map +rnd+ etc.; point out unavailable maps some other small tweaks and fixes

breaking news, we don't support typed consts anymore

Hopefully this change doesn't break anything
