* 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

Additionally, move the custom database load after the LoadStatus check,
so that they don't bring up the “fix your card database path” settings
dialog

This is the first implementation of a theme manager. It’s a rebased and
revisited version of #792.

The check was inverted. LoadStatus::Ok = 0, so only when
db->loadCardDatabase() returns 0 we know the card database path is
correct

+ Can be used for setting client size and closing the client.

Will expand on by sending client alerts to the tray.

Updated to push message notifactions to the toolbar

Preview image:

Added setting to enable/disable message popups

+ added translations for icon menu
+ removed maximize/minimize/restore from menu, not needed.

message bubble

        qDebug("Could not create " +
settingsCache->getPicsPath().toUtf8() + "/CUSTOM. Will fall back on
default card images.");

Checks if CUSTOM folder was successfully created. If not, prints qDebug message and proceeds as normal except uses default card images instead of custom ones.

Ref #127

It's always windows.

If the sounds path is unset in the settings and a “sounds” directory
doesn’t exists in the user’s data directory, install the sounds files
and set the settings value accordingly

 If none of the gameboard images is set and and the user’s data
directory doesn’t contain a “zonebg” directory, create the directory,
copy contents from cockatrice’s app bundle and sets the config
accordingly.
