Update Argument Structure

[jpoehls]

The current argument structure is based on convention and can get confusing really fast when arguments are optional. We may be converting to using a more named-argument convention instead of placement convention using Mono.Options.

From James Eggers: After looking more into Mono.Options (which is awesome) and the extensibility goals of DNM, there will be some difficulties getting the two to mesh well. With that said though, a modification will be coming to the argument structure.

This has been solved by creating our own argument parsing and validation framework. This will show up in version 0.7
