- Created Helper Class "GlobalStuffHelper" which contains global counter (ID for virtual Participants) and a list of URI's (Helper for the Listview in Main to associate its clickable views to the right project)

- Inicialized "yourself" as Contact in Main (Hack to be able to create Projects with yourself as admin (foreign key bug)), needs to be deleted as soon as the profile settings are done.

- Inicialized the ListView in Main to be clickable and open the Activity "Project Navigation" on click while commiting project data over intent extra.

- Modified "NewProject" to actually write Admin_ID into the OWNER field of database. But is still bugging around.
- Started implementing first start screen and fixed a few things.

Global helper is no more.
