Omgrofl interpreter with JIT support

This project aims to create a fully-functional interpreter of an esoteric programming language called Omgrofl. More information on the language itself can be found here: http://esolangs.org/wiki/Omgrofl

Suggestions or patches are more than welcome.

The interpreter parses the input source code and transforms it into an abstract syntax tree and then executes it. The syntax tree can be interpreted directly or JIT compilation into JVM bytecode can be used.

• Assignment (variable iz variable/value; variable to /dev/null)
• Char output (rofl variable)
• Char input (stfw variable)
• Infinite loop (rtfm ... brb)
• Loop break (tldr)
• Comments (w00t)
• Sleep (afk variable/value)
• Program exit (stfu)
• Incrementing / decrementing (lmao/roflmao variable)
• Conditions (wtf variable/value iz (nope) liek/uber variable/value ... brb)
• Stack/Queue (n00b/l33t/haxor variable)

• Unassigned variables are treated as nonexistent. If you try to use a variable without assigning a value to it first, an exception will be thrown.
• An exception will also be thrown if you try to take a value off the stack when the stack is empty.
• On EOF, 255 is returned as the value.
• JIT may or may not be faster than interpreting Omgrofl directly. It will definitely be faster if the program is long and resource-intensive.
• Indentation and whitespace don't matter. The only thing that matters is that every statement is written on a separate line.
• If there is more than one statement on a line, an exception will be thrown. This doesn't follow the language specification, but I believe this is a good decision, because a) honest mistakes will be found faster, and b) people new to the language will know if they've written anything wrong.
