v0.34 - REG instruction added

The new reg info file instruction can be used to redefine register names. Together with the mnemo instruction, this can be used to redefine nearly the complete disassembler output.

Might be useful if the GNU assembler or something like that should be targeted.

Attention: the documentation for the mnemo and reg info file instructions is in the wrong place in the documentation; these are not options, but info file instructions instead.
