* 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

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

Die roll now has a logo as it is correctly connected to the parent.

Updated to use the current deck size limit

Updated reveal top card to reveal top x cards
Sometimes you want to reveal more than only the top 1 card.

Addresses issue #1032

If a token is created with no p/t then the local db value will be passed
instead. If a value is provided then that will be used instead.

+ added more separators
+ swapped some actions from lib menu (scry action now higher)
+ Added capital letters to words

The problem was that back when I added #336 I made it so that if YOU
didnt recive the PT of the token, then it would be fetched from your
tokens.xml, the issue is that we needed to send that value to the
server. The server sees it as a 0/0

This fix will send the PT from the tokens.xml if available.

Felt like areas different to the current zone should be segregated.

+ Ctrl + N

Set to false by default, let me know if you think it should be true.

As all cards are played to the left of the screen this feels more
comfortable to use as you dont need to keep looking at different areas
of the screen.

Will auto rearrange when changed during game-play.

Looks better imo.
