* 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

With this update a new chat history definition is added on a per

TIL qt5 comes without mysql by default in homebrew...

Will need @ctrlaltca to confirm this wont mess anything up. I have
removed a option to se set from the cmake file. This option is not
needed.

Windows users, you will need to run cmake to create the sln again.

Protobuf depends on pthread under unix, but cmake’s FindProtobuf
doesn’t add -lpthread to link flags

* Use automoc instead of a manual list of headers
* Remove Qt4 detection
* Created missing .cpp for .h files (for automoc detection)
* Remove pthread linking
* Forcing -lprotobuf is not needed for mingw; msvc only?
