GB debugger: some instructions not assembling correctly

[njosro]

Some instructions such as "LD C, A" and others that have to do with the C register don't assemble properly. For example, LD C, A becomes LD C, $00 after clicking Apply. This causes the byte count to be wrong and actually overwrites one byte of the next instruction.

In this image I opened the assembler without making any changes:

Additionally, if you select a few instructions, then edit them with the assembler but don't completely fill up the byte count, it overwrites the "unused" bytes with EA.
