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
