Bugfix

Hi Adam,

Thanx for your effort, publishing your work in a nice Bundle! A php version contraint should be required. Copy de Trait in the Entity as you suggest, gives still type errors. The trait lang construct will simply not be recognized at php 5.3 and give a fatal error. Deleting this vendor file should not be the way to go... (but works for now)  A separate branch for 5.3 would probably give too much overhed, so I place a constraint in the vendor.json.

Secondly, there is a bug in the Definition FormType. The "select" option give some problems after saving, because this will render the SelectType Form Type which does not exists. I think, this has to be changed in "choice".
