GetPlugin v.1.0.3 — get filter match

Allows to use $ as the first parameter, followed by a definition tiddler
or section which must contain the following...

<the filter>|<the output>

In other words, when a tiddler matches a filter the corresponding output
is rendered, e.g.

[[TaggedFooTemplate]]
[tag[foo]]|<<tiddler bar>>

Obviously, this REQUIRES using the filter parameter.
