feeds_xpathparser 6.x-1.11

Let's see:

• Configuration options are now in a collapsed fieldset which makes normal node operations a bit tidier.
• Setting defaults now works as expected. If you set default values in the importer, the changes will propagate to existing nodes as long as they haven't been changed changed their settings.
• Got rid of the nasty form hack.
• Added tests to prepare for the DOM rewrite and general peace of mind.
• Much enhanced validation. Settings won't save if they have invalid XPath queries.
• #1043728: Patch: add encoding options for PHP tidy feature
• The mysterious thing where only an empty node gets added should be fixed.
• Variable replacement is more reliable.

I think that about covers it.
