Quick fix for some bugs.
Bug fixes
- fix module.unbind_proc sometimes not working as expected. huge thank to @CBeerta for helping with debugging
- remove ctrl+jkl as selection in emacs mode to prevent colliding with default emacs keybinds. use ctrl+n/p to select up/downwards
- change emacs mode's external editor keybind to ctrl+x ctrl+ee (double e for technical limitation), so that it won't collide with ctrl+e as moving cursor to line end
Other
- add external editor wrapper script to contrib with explination in readme.
