Changed how ROM_COPY and ROM_FILL are represented in tiny_rom_entry to be more how they were in the past

Browse Source 
Turbosub had a ROM_COPY declaration with an expression ('ROM_COPY( "main_code", 0x18000 + 0x2000,...) and this simply did not work with the new model.  This required changing ROM_* declarations to more resemble how they used to be and to perform the conversion on load.
