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

@ZeldaZach grammar nazi :) 👍

nice alignment over strict tabbing

- removed some info text since oracle imports all cards now and no longer offers sets selection
- added info about token
- `<br/>` --> `\n`
- capitalized `URL` --> http://www.oxforddictionaries.com/definition/english/URL

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

Requires #889

Additionally, remove an unneeded split() + join() call on every card
text

Translations have been updated.

Imported unzip methods from OSDaB-Zip project;
Adds a soft dependency on zlib to oracle; if lib if not found, oracle
will continue to compile and work but without zip support.
