Memory leak in DotCMIS

[Björn Kremer]

Hello,

I have just found a serious memory leak in dotcmis. The function 
"DeserializeElement" in converter.cs is leaking. I have tried to load a 
type definition multiple times without reusing the session object.(I 
have always created a new one.) The type definition contains a large set 
of "choices". Doing so will flood the memory. The memory leak is located 
in the XmlSerializer constructor. Please take a look at this article 
describing the issue: http://www-jo.se/f.pfleger/memoryleak Microsofts 
suggestion is to reuse the XmlSerializer class or to use another 
constructor.

Thank You
Björn
