Removed MESS roms

I removed the official MESS roms from my XML files There are a few files left unchanged for the following reasons:

**v1050** - Simple name change from v1050_flop done by another user. 

**msx2p** - This XML did not contain any official MESS roms.

**cpc646** - Simple name change from cpc_flop done by another user.

**launch4j** - Not a system XML.

**c64** - Does not contain any official MESS roms. Created by another user. Floppy games only.

**apple2p** - Does not contain any official MESS roms. Created by another user.

**bbcb** - Does not contain any official MESS roms. Created by another user.
