TiddlySpace safe mode

[jdlrobson]

I broke my TiddlySpace.
It would be great if I could do http://rakugo.tiddlyspace.com/#start:safe and just load the system bag plugins so I can fix my TiddlyWiki.

This would require hacking of the core.

FND will investigate this in later iterations.

Turns out there are two issuses to address here (cf. #33):

• only plugins from the system or tiddlyspace bag should be executed
• tiddlers for which an equivalent exists in the system or tiddlyspace bag
  should be ignored (inverting the recipe cascade)

The latter suggests a server-side solution is required.
