altered fileir.cpp AssembleRegistry() to detect if system calls fail, and to be more memory efficient.

Fixed some tabbing issues in core/fileir.hpp, added signature for fileir destructor in fileir.hpp. Implement fileir destructor in fileir.cpp. Multiple calls to generate spri no longer eat memory.

fileir.cpp, when assemblying the assembly registry, destorys any previous existing binary or assembly files, just in case.

Included new functionality in fileir to change the key of a registered instruction/assembly pair. This is necessary for some the rewriting I intend to do.

fileir now has an assembly registry. If assembling large numbers of instructions, register instructions here to speed up performance in assembly. Instructions are assembled on demand, or when fileir is used to write to the db or to generate spri.
