Merge branch 'development' of github.com:Kroc/NoNonsenseForum into development
Updated DOMTemplate, `html` is now a property instead of a method
Fixed unable to delete corrupted posts unless signed in

THEME CHANGE: class "nnf_error" was added to element `article.nnf_post`
in "delete.html"
Fixed #170: Appending double-encoding bug

With thanks to Stephen Taylor for reporting
Updating headers to v25 (not actual release yet)
Updated DOMTemplate to add an XML property to avoid HTML-specific cleaning in RSS/XML files and updated NNF to use this property for it's RSS/XML files.
Updating NNF with DOMTemplate changes
Fixed the iOS rotation / zooming bug, with thanks to TCB for testing.
Correction
DOMTemplate was updated to support HTML better with less depenence on strict XML.
The NNF theme has been updated to use less XML-isms. This doesn't affect any existing themes.
Updated NNF to work with latest DOMTemplate changes.
DOMTemplate now outputs by casting the template object to a string (i.e. `echo $template;`) instead of separate `html` and `xml` properties.
I thought I had fixed that!?
