v0.2.0-chrilley

This has the same filename as the ANSI version, so it will replace it. To get the ANSI version back, go to the /Extensions/Unicode/ folder and delete INI++15.mfx (the original MFX still exists in a different folder).

Changes include implementing a few new expressions in the NthItem family, and fixing a bug with the NthGroup expression.

NOTE: everything is still case-sensitive, as I have not yet decided the best way to approach case-insensitivity.
