Daddy32: Tasks Mode

Gives the user the opportunity to earn some credits for performing various tasks.

Known bugs removed, tested stability-wise, not so much game-wise.
Lots of to-dos and ideas still remaining, better balance between task difficulty and their rewards needed - please comment.

Usage:
Enter shop, open menu, select 'See available tasks'.
All tasks in the list are active, until they expire ('Days left'; day passes after each duel (won, lost or quited)).
You can finish any of the tasks and get bonus. For particular task, the bonus gets a bit smaller every day (until expiration).
