dmTag taggable models fluctuates

[fizyk]

It happens to me that I have different taggable models on different modules in the same project.
Recently I got unknown relation on admin's tag edit form (for taggable model). So I had to overwrite DmTagAdminForm and use $this->useField( array( 'id', name' ) );

We've got quite a lots of models taggable, some of them are using doctrine inheritance.
