Yay!  Figured out how to do this in VS2015!

Moved the updated hashing function out of the settingscache and into the
remoteclient and privatized the function for proper use.

ClientID is now generated on startup and stored in settings cache.  Then
upon connect there is a new SrvClientID generated from the ClientID +
servername being connected to

I'm working on a theme and realized we have a toolbar that used to be used for price, which we no longer display. I removed the code (and the unused price code action) as we weren't using either.

P/T column is really narrow. It should go before Card Type, so Card Type can expand into the remaining space.

Improves #1671, assuming I got this correct.

Untested!

 * 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

- `sounds` and `themes` moved into `cockatrice/`

moved subdirectory reference
`/cmakelists` to `/cockatrice/cmakelists`
