dump all keymap bindings for blender 2.65. the word 'key' here is in the colloquial sense as there are keyboard, mouse, and other map binding types. it's really an event dispatch mapping that happens to cover keyboards and other sources.

#there may be a better way to find keybindings but until I do, this will have to suffice...
#likewise, until i figure out blender addons proper, this will need to be pasted to the python console
