Some additions to select-slides.
Added draft for NameSelection in party-modes. Just extend CMenuPartyNameSelection in a screen.
Developer could use it or not, using it would make creating party-modes much easier.
More additions to this screen will come.
PartyNames: Added support for no teams.
PartyNames: Some theme-adjustments.
PartyNames: Added visual feedback for max-player-num.
Fix: HasFlag(EUserRole.TR_USERROLE_GUEST) does not work (workaround replaced it with !NORMAL)
PlayerNames: Change player/team-num on NamesScreen. TODO: Theme-stuff and remove options from config screen.
Revert PartyNames-changes on develop-branch.
