[fpc-pascal] FPC Docs updated

[Michael Van Canneyt]

Hi,

The documentation has been re-generated and put on the website.
the fpc/dist/2.4.0/docs directory on the FTP server contains 
also a version of the latest docs.

They have been re-generated from version 2.4.0.

Reason for the update is the complete documentation of the DB unit:
it has been finished, and adds roughly 200 pages (in PDF) to the 
documentation. I thought that was worth an update.

It may take a while before the mirrors catch up.

Michael.
