This change accomplishes two goals. The first is it moves the checking
for if the servers set user limit is reached out of the socket interface
and into the protocol handler portion of the code (were it should live).
It also eleminates the need for a DB query at login to check the user
count. The user account is actually already maintained by the server
and a function already existed to get the user count total.
Added the functionality client side to log users out of servers if they
are idle for more than 1 hour without joining either a game or room.
Sending a message (room/game/private) or performing a game action.
* main.cpp: removed path checking and db loading
* card database: merge card loading methods into a single one
* settings cache: take care of returning safe paths for decks,
replays, etc..
* main window: if db loading fails (eg. first run), propose to run
oracle
NSIS: propose to run cockatrice instead of oracle
Rework card database loading
* Move carddatabase-related method out of deckeditor tab
* Load cards in another thread and render them progressively
* Optimize database reload after enabled sets change
Fix deck editor column width
* removed the noCard hack.
* getCard() no more creates cards instead of just returning existing
ones
* Fix the “edit tokens” dialog.
* PictureLoader: avoid trying to download twice the same card
* PictureLoader: correct return of card background
* AbstractCardItem: avoid recalculating card color at every paint
Use a different file to save custom tokens
Misc required improvements
* Use nullptr;
* Refactor CardInfoWidget to use CardInfoPicture and CardInfoText
instead of duplicating code;
* Added CardInfo::getColorChar()
* Fixed some potential crashes
* removed dead code related to CardInfoWidget
* Don't require a restart after adding a new custom sets file
* Bump CMake requirements to 3.1
