Added script to generate PDF from scribus

### ManualPDFgen.py
#### Aim
A helper script to generate the PDF version of the manual from the marked down files in the repository, padded with the title and cover pages.

This works as a plugin for [Scribus](http://scribus.net], the free desktop publishing software, written in Python. It may not generate the actual PDF file per se, but will help in building the scribus (.sla) document which can then be tweaked manually and exported to PDF.

Currently contains only the skel of the script. Expect more commits.
