Some improvement when you get Available types. Used to return a new
array each time you call the function. It has been transformed into an
IEnumrable and yield return.
DisplayType, PreviousType and Watchsize have been moved outside the
Watch Class
So, I create a new dll named BizHawk.Client.ApiHawk and moved few stuff
to it.
Also moved some stuff to BizHawk.Client.Common. Don't think it can be
desiociated.
I started comment Watch and rearrange code (put some #region etc...
It compiles and it seems working :)
