Handles first pass of assembly

First pass involves the following:

1. read all lines from the main source file, following all "include"
   directives as appropriate
2. parse each line into a symbol, operation code, and operand as appropriate
3. each operand is evaluated for syntax and futher for value if there are
   multiple addressing sizes available; any undefined or not fully resolved
   value will default to the largest addressing size available (16 bit)
4. addresses are assigned to every symbol defined in the assembly
5. macros are defined and expanded at this pass
