Reorganizing into subprojects.

libpit      - Personal Issue Tracker core libraries (Filter, Issue, Project, Category)
pit-cli     - Command Line Interface (CLI) to libpit
pit-swing   - Graphical, Swing interface to libpit (built using Griffon)

libpit and pit-swing both build, though pit-swing is just an empty griffon poject.
