UserID Field added & lots of project stuff...

Successful Updates:
1) Added User ID field to Login Window
2) Added Project End Date field to Project Window
3) Added Project variables in create_project_window
4) Added Project getters
5) Added Tkinter-based timer displaying current time for reference

For Controller:
Do you want the view to create and maintain it's own dictionary with project viewers/associated tasks/etc or do you want each one passed to the Presenter as they enter them?  I think the first would be better but it's up to you.
