newRPL - build 1255 released! [updated to 1299]

[Claudio L.]

All unofficial ROMs were updated to build 1280.

Many bugs were ironed out in this release, I truly appreciate the work and dedication of our forum friend JoJo1973 for submitting report after report with all the inconsistencies and bugs he could find. We need more of that to make newRPL a really polished product.

This release saw operations with angles completely reworked so that evaluating symbolic expressions would produce the correct, expected result even when the user does some questionable operations on angles.

I updated the wiki explaining how operations on angles work so it's clear what this modification does. It's not foolproof and it may cause unexpected behavior especially in RPL sequences. If you use symbolic expressions, everything should work as expected.
