Argparse adoption

[shakna-israel]

Rather than manually writing up handling for each command-line argument, use the in-built argparse library. Fixes #45, and makes most other issues simpler to fix.

Current Issues:

• Breaks backwards compatibility. wontfix
• Even if given an input file, but not an output file, it will assume you want to build for Docbuilder. Fixed in b6f48ff.
• Doesn't seem to create files correctly, so doesn't actually build any documentation. Fixed in 1b45c53.
• Tests need re-writing.
  • Fixed in 3d1a82673bd06658f8f41b78b85848842a76eba7

Repository health increased by 14% when pulling 9ea5944 on argparseAdoption into f934c9b on master.

• 1 new problem was found (including 0 errors and 1 code smell).

New Issue:

Every time getFlags is called, Docbuilder checks to see if the output file exists, and if it does, kills it.

This is temporarily disabled, but may cause problems if the file does exist before Docbuilder is run.

b6f48ff fixes it so you don't have to specify an output file, Docbuilder will attempt to guess it.
