So, I guess this encompasses issues #5, and #25, and quite possibly some that I've missed this morning, due to chronic sleep deprivation. Regardless, the last commit held the first of the code, for this particular aspect of things (see commit 9068f51).

The system will just going to use a text file, with semi-colon signified comments on newlines, and key/option pairs, both strings, delimited by a ": " betwixt.

The aspect that has not been touched in the code, yet, is development of a new Form, in order to handle assignment of the options, from the user's end. That'll be pretty simple, I'm thinking.
