selfspy option to not record special keypresses as repeats

using the `-r | --no-repeat` option forces individual recording of
special characters. Special characters have been recorded with a count
integer <[Backspace]x2>. When using `-r | --no-repeat` the same 2
characters will be recorded as <[Backspace]><[Backspace]>.
