fix #1777

Fixes #1529.

Completely untested, because I don't think this could possibly interfere with anything. It's a straight revert.

 * Removed remaining picture handling from card database and cardinfo
 * removed the “noCard object” hack

Fix #1499, Fix #1493, Fix #1477
Fix typo

Moved setting files & Added code for a future portable build

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

Game types are only available in online games.
This is the fastest fix.
Replays now work again.

+ The game type(s) is now displayed in the tab
+ Reformatted tab title

Updated to trigger on receive rather than send

Related to #808

When closing the app/game tab with a zone revealed the client will
crash. This was due to the zones not being deleted.

+ Removed unused buttons
+ remade button art
+ fixed crash with font colors/replays
+ removed unused timestamp label in replay

Before:

After:

Add a configuration toggle to enable alerts when spectating.

Default behavior is to not alert.

Games with only 1 player will now not focus on the chat when starting
the game. This helps with goldfishing.

+ Added room name
+ takes you to kicked game tab

Two regressions; depends on the fix for #684, too
