Add support for the shift modifier.
Because keyboard layouts vary, the shift-modifier `<s-…>` is only supported for special keys (like `<up>` and `<home>`) and for ASCII lowercase where we assume the shift-modifier just produces the matching uppercase character. Even that's not universally true, since in Turkish `i` and `I` are not an uppercase/lowercase pair, but Kakoune's default keyboard mappings already assume en-US mappings for mnemonic purposes. Mappings of the form `<s-x>` are normalized to `<X>` when `x` is an ASCII character. `<backtab>` is removed, since we can now say `<s-tab>`.
