FirmWeave 2.5 rc4 added

Noticed there was a small bug in how local vars were being defined; while I was in there I squeezed a few more bytes out of the board format and added a few local counters.

= 1/23/2022: 2.5 rc4

Bugs Fixed:

• Off-by-one error in board and object locals.

Improvements:

• Board locals increased to 7.
