Game feel improvements

Well, it's been a while.
As it turned out the mod selection menu didn't work properly, it would only display imported mods, but wouldn't allow to select it :(

Windows build remained untouched, sorry

As for the improvements:
A new cute skin pack is now bundled with the game
Added a Russian language localization
Replace the container skin
Reduce the container size to fit into the screen
Added a score increase animation
Mostly fixed collision bugs
Improved music player shuffle
Added a red screen overlay alert when a suika is above/outside of the container
Made suikas fall faster
Reduced the next suika spawn and drop delays
Added a combo number popup
