v0.13: Mobile UI, challenges, new mechanic

Game UI was adapted for mobile browsers and touch-screens. Although less convenient than on desktop, game should be playable from your phone now. Remember that you can transfer saved games between devices by using 'copy to clipboard' and 'enter as text' buttons in save-files window.

Game now has additional achievements which do not unlock anything and simply offer additional goals and challenges.

New 'redirect' mechanics, although rare, may be quite game-changing. It allows some unusual builds and hard-counters some tricky monsters.

Major gameplay changes:

• New status: 'redirect'. Redirects status-changing effects from hero to monsters and vice versa
• Only works on statuses which are applicable to monsters (e.g. works on strength, but not intelligence)

Minor gameplay changes:

• Added 13 challenges -- achievements without unlocks
• Unlocking ascensions now requires only 6 heroes unlocked

Major UI changes:

• UI is now suitable for mobile clients
• Improved UI responsiveness to different screen sizes
• 'Clickable hint' setting is removed, hints are now always clickable

Minor UI changes:
