Changes to imageCropper, supports new mediafilesystem
Fix U4-4119 - Export Fails for Generic Properties

Adds null checking for PropertyGroupID on export so that properties with
no group (tab) don't throw an exception.
PackageService: Fixes Single import for DataTypes

Importing a file with a single data type failed, because the DataType
element is at the root when exported.
fixes most of the newly failing unit tests and adds better null checking
fixes another test
updated to latest examine
Added the ability to specify explicit db type's for a property type using an overloaded ctor argument. This allows us to specify explicit db types for properties without having them get overwritten during the repository saving logic which will always reset it to be the db type of the underlying property editor. In the case of our built-in membership properties we do not want this to happen. Fixes some unit tests. Removes built-in props from being included in the property types on the profile model on the front-end.
fixes reflected property on dynamicnode and unit test
fixes some permission logic and a unit test
Updates some method names to be less confusing regarding permissions
Changes some of the naming conventions for the underlying membership provider services bits.
completes: U4-4275 Hide built-in member type properties from the insert umbraco field list
Use the database "agnostic" query for this (see U4-3876)
Update UI.Release.xml with the correct Partial View references
Been a while: properly syncing /config/*.config with /config/*.Release.config
Update incorrect summary
Apparently we rely on <error404>1</error404> to be in umbracoSettings.config
Fixing some potential upgrade issues and two issues found with the legacy member API

- For legacy API we never had and "approved" checkbox, so the assumption is that members are always approved
- The RequiresUniqueEmail check was wrong, previously the assumption was: if there's no e-mail then don't check for uniqueness
Adding missing CreateMember method that also as a convenience allows you to pass in the member type alias instead of a whole membertype
Removes new member service Creating event, as only Created makes sense. Deprecates the other 'Creating' events with a note to just use the Created event.
