v2.5

The .gsh directive has been enhanced to provide full support for all geometry shader operation modes (point, variable-sized primitive and fixed-size primitive). This also effectively separates vertex shader uniform space from geometry shader uniform space.
The .out directive has been enhanced to allow wiring semantics to any arbitrary output register. Additionally the dummy semantic was added while the 7 semantic was removed.
Added auto-insertion of NOP instruction in corner cases involving flow of control instructions, together with the --no-nop directive which instead of adding NOPs warns the user about the corner cases.
Added support for rgba and stpq in addition to xyzw.
Added an error message for invalid input register use (e.g. add r0, v1, v2).
The operand descriptor allocation algorithm has been enhanced to take into account unused operands.
The 6 and 7 conditional operators have been removed since they actually do not exist.
Really corrected MAD instruction encoding.
Several miscellaneous issues were fixed.

(Breaking change) Command line format changed.
Added support for assembling multiple shaders (DVLEs) into a single SHBIN.
Added new directives: .entry, .nodvle, .gsh, .setf, .seti, .setb.
Added auto-detection of inverted forms of opcodes. (Explicitly using dphi, sgei, slti and madi is now deprecated)
Several miscellaneous bug fixes.
