Add new opcodes

[avosirenfal]

This adds a new test opcode that attempts to acquire a named lock and branches depending on whether it could or could not instead of waiting to acquire it.

I've also added a break opcode that brings you to the nearest loop exit just like it would in any other programming language.

Here's a simple test program with two loops I used to verify break works correctly. I'll be testing both instructions on a large playthrough of Age of Engineering over the next few days.

That was harder to make than the code in the pull request was ._.

I will check all this out later. Very hard at work with the rftools builder right now. Thanks

Updated to add float versions of all the numeric opcodes (add, subtract, multiply, divide, modulus).

These are very useful for vector art screens. Here's an example program for a Mechanism tank display:

Add a redstone pulse opcode. Add a CPU limting opcode or a function so we can set it to a specific op/t. Add a splitter opcode.
