New roster hero select screen

Changes the character selection screen before starting the game queue. The interface is based on a leak from the experimental version of the game.

There are two versions

v1 Made initially and attempts to copy the original layout with minor inaccuracies. 

v2 Based on v1 with changes suggested by Fred that improve the interface. Character tags and a colored background that changes depending on the character selection have also been added. Please note that if you have the “Force English hero name” setting enabled, the second version will lag.
