Python Project Properties - Update: Licenses

[ebresie]

As of v0.3.0, when open project properties, many of the field do not populate correctly and have placeholder logics. This issue is to resolve this.

Python Project Properties: Licenses - Save/Load licenses values properly from project properties. This may need to be further expanded to pull in a list of possible licenses and when needed, include a copy of this as an external file

This updates further relative to the initial project properties added as part of #20 updates.

Need to see if default NetBeans licensing functionality can be usable here (i.e. pull list of licenses, access to the text of a given licenses, etc.)
