DCPU-16 Syntax Highlighting

<?xml version="1.0" encoding="UTF-8"?>

<!--
What follows is a primitive .lang for syntax highlighting of .asm files. It highlights all of the opcodes listed in version 1.1 of http://0x10c.com/doc/dcpu-16.txt. It also highlights JSR, which isn't listed quite as clearly as the others. It is intended for use with graphical editors on Linux, such as gedit, but may work elsewhere, as far as I know. On Linux, place the file (which can be named anything with a .lang extention, but preferably something like dcpu-16.lang) under
    /usr/share/gtksourceview*.0/language-specs/
