First QOL improvements and bugfixes

First week of CORB's life on Steam has passed. I've got numerous suggestions on how this tool can be improved and I've added few changes: [list] [*] Added board orientation switching on openings graph screen [*] Saving the game settings for your second playthrough [*] Added searching for openings by playing the moves on the board [*] Fixed bug with AI not being restarted fast enough when ELO is changed on match screen [*] Added "turn off AI suggestions" feature for correspondence players [*] Added resizing of opening move info panel [/list]
