Fix U4-4779: Media Picker not working as single picker
Fix for issue U4-4826

When editing an existing link in tinymce the following error is thrown:
Could not find the tree content, activeTree has not been set 

This is caused by passing a wrong value as parameter to the doLoad method in the loadActiveTree function.

I simply placed the container a little higher up, just above the Save and Publish buttons.
Fixes: U4-4420 TagQuery / TagService missing method to get content with tag.
Fixes: U4-4211 User without media section permission will be logged out immediately when accessing a document type using a media picker datatype (u7.0.3) - this is done by using the entityResource in the mediaPicker but to do this we need to return a cut down version of the media properties in the additionalData which is tricky because the cropper stores json which is ntext and the existing sql didn't cater for this. This also cleans up the entity service and we no longer have this internal collection of properties, everything is just added to additionalData, then had to add mediaHelper method to deal with getting urls from a media 'entity' not just a media object.
