Rewrite assembler

This is an almost complete rewrite of the entire assembler from the
ground up, with a different parsing strategy and a whole new symbol
resolution mechanism for automatically including library files.

The assembly syntax has also been slightly modified, with padding
tokens now being prefixed with '#' instead of '$', and a block-style
anonymous-label syntax which uses the '{' and '}' characters.
