Cleared the default mapping of hotkeys as they were conflicting with the key shortcuts.
Removed the Open, Change Disc, Refresh List and Exit hotkeys as they work only when driven from the menu.
- Simplified the locking mechanism when controllers were updated
- Reloaded the config of the controls instead of re-initialising the control plugins
- Fixed controls being unresponsive after the Refresh button was pressed
- Disables the hotkeys while the controller config is open
* Halving the number of hotkeys checked for (there were extra for future use)
* Gets the controller status once before parsing hotkeys
* Checks for the GUI lock once before parsing hotkeys
* Removed some redundant memsets
