Normalize mappings

[runiq]

Modes now use lowercase keys, mappings use the internal representation via nvim_replace_termcodes().

So I thought about this... but doesn't this make it impossible to map J?

(I do need to fix it for the "" vs. "" business though)

[tjdevries]

I was thinking maybe we should use this: nvim_replace_termcodes({str}, {from_part}, {do_lt}, {special}) ?

[tjdevries]

since that might change <CR> and <cr> to the same item.

[runiq]

Oh that's what that is for! Sure, will do tomorrow. Gotta tuck the young'un in now I'm afraid

[runiq]

So the applied_mappings table uses the internal representation now since those are normalized, but telescope_map still gets the original, non-normalized mapping. The reason for this is that nvim_buf_set_keymap() unconditionally appears to run its input through nvim_replace_termcodes(), and running that twice isn't necessarily idempotent (the <up>/<down> mappings break, for example).
