Add Event Sources:event_sources

- Add source property in Action and EventFilter
- Change TPropContainer contructor to accept keyword arguments and set
  properties that were given
- Change every single TPropContainer subclass constructor to accept
  kwargs and pass them on to super init
- Add a "null" option for TStringProperty
Use Event Sources:
- Make the probe require a source property to install or subscribe
- Have ProbeProxy install and subscribe return a prefixed address
- Make update, uninstall and unsubsribe extract the prefix from the
  address
- Have the TutorialRunner set a source on actions/events before
  installing/subscribing instead of setting current activity on
  ProbeManager
Test Event Sources:
- Change the tests according to the new constructors and behaviors
