import tiddlers from a TiddlyWiki

[psd]

I'd like to be able to import tiddlers from an existing TiddlyWiki, either from a URI or as a file upload.

I'm concerned that at this point, while TiddlySpace is still rapidly evolving,
encouraging the import of regular TiddlyWiki functionality (themes, plugins)
might be troublesome.

In particular, there's no safe mode yet (#53) ensuring users are able to revert.

Please see http://github.com/tiddlyweb/tiddlyweb-plugins/commit/1382ac6635739c3e7e50888583eb923d637692ee and http://svn.tiddlywiki.org/Trunk/contributors/BenGillies/TiddlyWeb/Plugins/Importing/tiddlers/TiddlyFileImporter.js for initial work on this.

Regarding the destructive potential of importing:

After Bauwe had imported an existing document (from TiddlyHoster, using my
uploadToTiddlySpace hack), his space became unusable - to the point of not
being able to restore it himself.

Turns out he had (unwittingly) uploaded TiddlyWebAdaptor, TiddlyWebConfig and
ServerSideSavingPlugin, causing all sorts of JavaScript confusion - so I had to
delete those tiddlers manually on the server.
In addition, I also had to rename (disable) his custom PageTemplate,
ViewTemplate and EditTemplate.

(Perhaps this warrants a separate ticket, beyond #53?)

This can be closed now.

basics seem to work, with some warts which presumably will be worked out, so closing
