Default Package Detection

Javatar will specify default package with these steps...

1. Source Folder specified in current project file (when open project)
2. Project folder in current project file (when open project or folder)
3. Folder contains current file (when open file)
4. Specify current package as (Unknown Package)

Javatar will refuse to create packages or classes within unknown package. In this case, mostly because current file is not on the disk yet.
