Code cleanup
Closes #16
Added startValue attribute to entities.rng to define start value. Only one is expected for each dialog.
Added startValue parameter to popCreatePerson, popCreateOrganization, popCreatePlace, popCreateTitle to start dialog with a value in defined startValue place.

startValue will be added where it is defined even if it is not a required value.

To test this text input boxes now appear on the test application. Their values will be added to the starting creation dialog.
