Version 0.38.1

v0.38.1

• Added a __del__ method to MSGFile to ensure a bit of proper cleanup should all references to an MSGFile instance be removed before the file is closed. OleFileIO doesn't appear to have one, so it's up to us to ensure it is properly closed. Note that the del keyword does not guarantee the immediate deletion of the object, and you should take care to close the file yourself. If this is not possible, importing the gc module and using it's collect method will free the files if your code has no references to them.
• Fixed an import issue with signed messages.
