Added basic transition system that works with GameApp's phases. Currently does a fade-out between elements, which works well in some places and not-so-well in others. We'll definitely want to think about where and where not to use it... they'd work a lot better if we could spawn a thread to handle loading the next state while transitioning.
Also cleaned up the shop a bit, so it uses ReadButton() instead of GetButtonClick()-- hence the slight change to JGE. Added a tiled image for the task board, which loads conservatively (I tried 128x128, but it didn't look as good).
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).
