No "Internals" tab in control panel

ModuleType.tid refers to a non-existing "Internals" tab in the control panel for a list of module types used in this wiki.  I propose listing these directly in this tiddler as an alternative.

Fix problem with Maruku Markdown metadata

Fixes #855 - albeit it’s a bit of a kluge. The internal format returned
by `markdown.toHTMLTree()` isn’t sufficiently well documented for me to
be confident that the new code is resilient to all the things that
might be returned.
fixing many obsolete ~ signs. modify setfield.js to get consistent language settings
get default language files back
Clarify select widget docs
