Clearer explanation of key descriptor syntax
Add support for autosave

Causes the wiki to be autosaved whenever clicking “done” after editing
a tiddler. Only works with savers that support autosave. We should
probably make autosave configurable
getRelativeDate: support for negative deltas

Add support for format="relativedate" to be used when the date is in the future.
oops, actually correct delta

Actually change delta to a positive number to get the logic the same.
Fix problem in server with URI encoding of titles in etags

Fixes #398
Force position:relative on tag pills

This avoids a problem with tag pills not working properly within table
cells.
Add automatic saving and warning on exit with unsaved changes

We re-use some of the existing syncer mechanism. It was already keeping
track of changes to tiddlers in the store when working with a tiddler
syncadaptor. Now it also tracks changes when there is no syncadaptor,
allowing us to provide a warning if there are unsaved changes.
Move some system tiddlers into the right name space

The tiddlers temporarily used for adding new fields and tags should be
in the $:/temp namespace so that they don’t dirty the store
Docs updates

Refactor the theme switcher to be a generic plugin switcher

Update control panel text
First pass at language plugins for internationalisation

Still quite a few details to work out, but this shows the basic idea of
re-using the theme mechanism to handle language plugins.

Comments and questions welcome.
