Intel 8080 Syntax Highlighting

Adds proper syntax highlighting for intel 8080 mnemonic assembly.

Note: by default, syntax highlighting is applied automatically to all files with any of the following extensions: 8080, 8080asm, i8080, i8080asm.

VIM's assembly highlighting was designed with x86/x64 mnemonics in mind, and as such, it doesn't quite work for code written in Intel 8080 style mnemonics. Though it's more time-appropriate to use no syntax highlighting for Intel 8080 assembly, I will admit it is much nicer to work with highlighting, and I'm confident you'll agree.

You can view individual examples here: Plugin Highlighting, ASM Highlighting, and No Highlighting.
