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.

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

fixes #1520

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.

After adding a card to the main or side, the search text will become
selected to easily start the next search

fixed welcome msg
added some articles
added database phrase to card updater
cosmetic changes to the description in edit sets
