binds...
* tex bro: left double click loads directory, containing active shader + focuses on it
right double click loads 'common' directory
misc...
* shader editor gets focus after been hidden behind main window and called again
* patch thicken: significantly more fail safe; correct handling of cycled patches
* fix: was parsing vfs twice; pk3s were being opened twice during runtime
* fix: shortcuts work after startup (plugins bar buttons were stealing focus)
