[issue8832] automate minidom.unlink() with a context manager

[Kristján Valur Jónsson]

New submission from Kristján Valur Jónsson <kristjan at ccpgames.com>:

It is all to easy to forget to "unlink()" minidom documents resulting in huge memory usage.
This patch allows to automate that process with a context manager, similar to how files can be closed in the same way:

with xml.dom.minidom.parse() as dom:
    workwith(dom)

will automatically call dom.unlink() when context manager is exited.
Patch provided.
