Example: <txp:output_form form="test" cache="3600" /> will be cached for
1 hour, unless the site is updated meanwhile.

Brings the power of more easily managing prefs, updates and installation from flat XML/JSON files, including loading content from XML files.

Many thanks, makss for this awesome work.

Reworked imageFetchInfo()…

Great stuff. Thanks, Jeff. Two more annoying tags deprecated!

Also, remove second comment example

Fixes #883

It looks messy. Plus the only thing of importance to upgraders is the
pre-flight check. Anyone who wants the full experience can refresh the
page.

Also switch logic of update check so it tries json_decode() first. The
JSON function fails more gracefully than unserialize() as it doesn't
throw an E_NOTICE.

Fix feed warning + formatting output

See #887

Also added link and form attributes

Also move Override Form into the Sort and Display area, ready for the proposed move of the markup blocks inline with their designated fields. Advanced block: your time is almost up.

Keeping the dropdowns for now. Consider either:

* AJAX popup, similar to the tag builder?
* jQuery to swap the fixed text string containing the currently used filter for a dropdown, and back again after selection?

Todo:

* Remove the inline help twisty block.
* Figure out how to serve the correct pophelp topic from the new 'i' links.

Unnecessary additional category wrapping div has been removed.
