Bug fixes and stability improvements, mostly.

Changelist:

• Fixed: users with non-english usernames were unable to launch the game on Windows
• Attempt to fix the game not launching on some AMD GPUs
• Selected abilities are now synchronized with the cloud and are not stored as a device-specific setting
• Rare - Legendary cases and blueprints became a bit cheaper on the market
• Fixed: Sniper's killshot and Flamethrowers ultimate ability did not kill some enemies during Overload
• Improved quality, size and resolution of JP, KR and CN fonts. Added missing symbols
• Fixed: desync check failed on levels 1.8 / 2.8 / 3.8 / 4.8 (false positive, actual repays are fine)
• Improved sync check reports for Lua scripts
• Added game integrity check, used to ignore crash reports from a modified versions of the game. You can view files integrity status at the bottom of the settings screen and, if it failed on PC - try to check local files integrity through Steam
