The profiles used are decided as follows:
1. 'validator_profiles' property of the harvest source config
object
2. 'ckan.spatial.validator.profiles' configuration option in
the ini file
3. Default value as defined in DEFAULT_VALIDATOR_PROFILES
Tests are passing, apart from a couple which didn't work before:
* test_functional.py -> functional/test_package.py (3 failures in 4)
* functional/test_dataset_map.py (1 fail in 1)
There may be some code errors still untested.
Renamed Validator -> Validators to make more sense.
