[Plugin: Crayon Syntax Highlighter] Added feature

I also added a feature to pull a named block of code out of a file based on a tag.

Here is an example use case:
http://answers.drunkencoders.com/

Usage:
<pre url=”my_source_repo” block=”name” >

code not shown…
code not shown…

comment with the string “{b=name}”

code shown ..
code shown ..

comment with the string “{b=name}”

code not shown ..

This is very useful for me as it keeps my tutorial source code up to date (all i have to do is update them from source control and the tutorial code is valid).
