Hope add `subType, mapKeyType` to annotaions `Embeded, Property, Reference` #274

I hope we can specify these types, because when I use morphia in scala, I found 
scala will drop generic type information of collection fields defined in traits.

That means we can't use traits to reuse some code if there is a collection 
field need to be declared in trait.

Please see this question:

I have fixed it in my own project by adding `subType, mapKeyType` to 
annotations `Embeded, Property, Reference`. When mapping, I will first check 
these annotations to get these types.It works well now.
