Extension:Pdf Export Dompdf

Overview
This extension is a modified version of the Pdf_Export Extension. See Extension:Pdf_Export for details.

I modified it because I wanted to do pdf-export on my shared hosting server. It was impossible to install htmldoc on it because I dont't have root access.

Searching the web, I found dompdf, an html to pdf converter written in php5.
