Check if a user already exists

[GoogleCodeExporter]

We should add an additional Validator in the users form that checks if the 
username isn't already in use. 

This kind of validator may probably be useful in other forms as well.

Since I need to develop a new validator, I'm moving this to the 0.3 release.
The new validator will check the database using 5 parameters:
- Table name
- field which contains the value
- The value that needs to be checked
- A field name used to ID a record which should be skipped (in case of an 
update)
- ID value of the record that needs to be ignored
