Debugger RAM pane shows unmapped ET-3400 range

[ricknun]

v0.2 Beta -- The Debugger, Disassembly, RAM display shows $0000 to $03FF but only $0000 to $01FF is in the ET-3400 memory map. It seems the RAM display should stop at $01FF. Or if it is because the emulator is meant to allow more memory than the real ET-3400 perhaps add a built-in label at $0200 saying "; BEYOND ET-3400 RAM" or similar to warn users that use beyond that point can't be run in a real ET-3400.

A related suggestion: Built-in Disassembly labels at $0000 "; ET-3400 USER RAM (197 BYTES)", $00C5 "ET-3400 MONITOR RAM (59 BYTES)", $0100 "ET-3400 OPTIONAL RAM (256 BYTES)".

A thought regarding the built-in RAM labels I suggested above -- If there ever is a user-provided label whose range overlaps one of the built-in labels, the user-provided label should hide the built-in label.
