1d8c0c9c46 eZ80 Follow-up
- Added RCEZ80 platform option to Build.ps1
- Added EZ80 config settings to MASTER config (required to get build to work for some situations)
- Modified a .EQU in cfg_RCEZ80.asm to a .SET.  After adding config setting to MASTER config, the .EQU was causing a redefinition error.
- I have temporarily removed some "TRANSLATE" lines in ez80uart.asm.  They were attempting to place a value greater that 0xFFFF in a register and generated an assembly error.
- Modified a few JR instructions in hbios.asm to JP due to out-of-range errors.
- Modified std.asm to "nest" a conditional.  The Windows assembler does not ignore the remainder of a complex conditional when it should.
- Modified tms.asm to replace the PRTS macro with alternative lines.  The Windows assembler cannot handle a string longer than about 8 characters in a macro argument.
- Added the TIMER utility to the ROM disk.  Not sure what happened there.  It was included in the Windows build, but not the Linux build.  There is room for it, so I added it to the Linux build to get a binary exact build compare.
