Bugfix, own collection

Using RMB on menus to change hotkeys was broken.
- the input button was on a weird place outside menu, assign
  would close pulldown, so you had to reopen to check
- ESC didn't close the button, but assigned ESC as hotkey.
  This key is a protected key, and always should be escaping.
- Worst bug: if you used this on a 'user keymap' it removed
  all entries from the map...
