DiscussPlugin v.0.9.1 renamed and fix for non-existing tiddlers

Prevents from showing when tiddler doesn't exist yet.

A rather simple plugin to render Disqus in an iframe in a TiddlyWiki on
TiddlySpace.

Will *not* work in a classic TiddlyWiki unless you hook-up a proxy
server via php et. al. and so some url rewriting that captures the
desired individual url's as needed for disqus to work.

Hashes won't do!
IconTabs icons .— added TabScripts icon
ListFiltrPlugin v.1.0.2 — preserve selector

The preserve selector either via parameter or global configuration
prevents listfiltr from hiding stuff inside them, e.g.

Say you have a...

<box><match/><ignore/></box>

Previously <ignore/> would have been hidden, with preserve you can say
that box should be preserved resulting in <ignore/> to be shown still
while only<match/> would be highlighted.
ColoredLinksPlugin v.1.0.3 — just ignore

nothing changed, really
