Bug fixes (Hotkeys, multiple same-name files, background color)

Fix hotkey system
Fix issue where opening a non-class file of the same name in two different containers to show the contents of only one file
Set the background color always because in some cases the default color was blue (?)
Bump version number

Fixes #1
Fixes #2
