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.

When the assembler encounters an error, the erroneous line and the line
number are output in order to help the user to find where in the input
file the error occurred. This is useful for single-file inputs, but the
line number is generally not helpful if the input file was generated by
concatenating multiple files.
In order to help the user to determine where in the program source the
error occurred, the assembler now reports the name of the label which
directly precedes the erroneous line.

This will break unix pipelines in order to prevent any emulator down the
pipeline from attempting to run a malassembled program.
