NLS: Drop two math sequences, slightly clean up APL sequences.
- Two compose sequences containing
leftshoe
andrightshoe
are dropped as no keyboard layout uses these keysyms. - The compose sequences for
therefore
andbecause
in the APL block are moved to ascending Unicode order. - The comments for the compose sequences for
U2299
are corrected to more accurately reflect its sequence nodes and its real name in Unicode.
