Added documentation, removed debug prints, implemented printing.

Documentation was added to the config parsing file.

Debug prints were removed from the server main script.

Printing was implemented on the client side for tasks retrieved from the
server. Need to fix:
    - lines longer than max length don't max out the length allowed
    - long lines don't wrap at words
    - completed shows a 0/1 instead of something more readable
    - prettier header names
    - possibly repeat tags or make them bolder somehow
