[TiddlyWeb] saving implementation is inconsistent with TiddlyWiki core

[mahemoff]

In these adaptors:

• calling saveChanges() leads to the default (not overridden) warning dialog (because the wiki is served from  http://, it incorrectly assumes the changes won't be persisted)
• calling store.saveTiddler() will persist the tiddler (by uploading via PUT), whereas in core, it would only change the memory model and saveChanges() would then need to be called

For now, my workaround is to rely on saveTiddler() and to clear window.saveChanges(). I believe the long term solution would be for these adaptors not to override saveTiddler, and instead override saveChanges().

After discussing this with Saq, Chris and Mike, it turns out that the issue is more complicated than originally thought because not saving immediately (e.g. when offline/unplugged) means local changes might need to be tracked.
