PHP 5 port of Markdown, plugin-based

[Paul M Jones]

Hi,

First of all, thanks to John Gruber for the fantastic Markdown syntax  
and parse/render system.  Also, thanks to Michel Fortin for his PHP 4  
version of Markdown.

Based on those two works, I have completed a **plugin-aware** PHP 5  
version of Markdown.  You can see it in Subversion here:

* <http://solarphp.com/svn/trunk/Solar/Markdown.php>

* <http://solarphp.com/svn/trunk/Solar/Markdown/>

Every Markdown rule is now a plugin, and new plugins can be added  
into the processing stream.  I have taken some liberties with this  
implementation, such as using delimited integer markers instead of  
MD5 hashes, and changing some of the rule names (e.g., from "Anchors"  
to "Links" in one case, and from "ItalicsAndBold" to "EmStrong" in  
another).

Solar_Markdown comes with unit tests for individual plugins, and  
passes the MarkdownTest suite John has so kindly published (except  
for the "advanced inline html" test, which apparently nobody passes  
at this point).

* <http://solarphp.com/svn/trunk/tests/Test/Solar/Markdown/>

I'm happy to take feedback and suggestions for improving the code,  
and I hope it can be of use to any PHP 5 folks who love Markdown.
