* Add new service to handle profile migrations
* Handle various null checks
* Remove unecessary assignments
* Further works on this:
- Loads profiles as JObject's initally, so migration can take place on profiles that don't have proper compatability
- Adds prerequisite migrations, and sorts them after one another
* Throw exception if profile can't be deserialized after migration
* Cleanup & use profile version
* Further migrations work, support 3.10 & 3.11 profiles upgrading to 4.0
* Update parameter name
