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.

The JMP and JSR op-codes no longer include a * character, and the
double-mode JCN op-codes have been changed to JSN to reflect a change
in the instruction set of the Bedrock processor.

Double-quoted strings are automatically terminated by null bytes, with
single-quoted strings maintaining the prior non-terminated string
behaviour.
