Core Keyremap Allow setting keymap from plugin

Browse source 
Allow setting and removing keyremap on the fly

It was pretty annoying trying to work out a keyremap with a restart
required to set the remap and was quite annoying when I was no
longer able to navigate to the plugin or filebrowser due to setting
the wrong remap

now you can try out a keymap and if it doesn't work a restart will
sort things out
