* 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

 * uninstaller: delete zlib1.dll (first issue in #876)
 * require the user to uninstall the old version before installing the
new one
 * use project-version as branding name (fourth issue in #876)

Remove argument that if added by default with out having the proper configuration defined during compiling would cause cockatrice to not open properly.

There are extra quotes introduced into line #19 that causes the NSIS installer creation to fail.

Servatrice icon now gets created in windows start menu.

just avoid deleting servatrice.ini, if the user manually made one from
the servatrice.ini.example

Package the correct cpack’s temporary directory

* Move all cmake-related files in a new “cmake” folder
* move nsis files in there, too, since they are templates parsed by cake
* retrieve git version once when cmake is run, and use it for both
creating version_string.h/cpp and for package naming

Putting user stuff in program files is bad

This should prevent deleting old deck files
