v1.1.6 - Improved mod updater

• Mod updates will now be served in a list instead of individual prompts per mod.
• Updates will no longer silently fail; retry prompt showing which mods failed will now appear.
• Mod updates will now be done "atomically", meaning if one file fails to download but the rest don't, none of the files will be updated. This ensures files don't have a version mismatch and thus potentially break the mod.
• More clear error messages in console. Exceptions are properly handled now and logs will show what file failed to download for what mod.
