Added T2 presentation

Added the T2 presentation (in ODP and PDF formats) as it may help in understanding the architecture of it.
Minimal fixes to generic_minimizer.py

Fixed a small bug removing duplicated elements from the list of positions to try.
Also, display more information for each iteration about the maximum total number of tries to wait, etc...
Enhanced the OLE2 mutator multiple mutator

If the directory with samples selected for the projects contains too many other type of files, it often sends back an empty ZIP file with no mutated OLE2 document at all. There is very little we can do here but, at the very least, we can try to iterate 2 times the number of files the user wants to generate before giving up.
Added iteration option to finish a project

Added the maximum iteration option. When the maximum number of iterations is reached no more samples will be created for the specified project.
Reset iteration after a crash

Reset the iteration counter after a crash happens.
Bug fixes

Fixed the horribly coded (was I drunk?) generic_client_server.py fuzzer.
Fixed a small bug in NFP engine: No samples would be created for projects created before adding the "maximum iteration" option.
Fixed bug in the web frontend

After the latest changes (the maximum iteration feature), adding new projects would fail.
Update install.txt

Add the URL for Beanstalk server. There are some distros/operating system, for which there is no easy way to install (like apt-get install).
Create SAMPLES_PATH directory if it doesn't exists

Fix for issue #15 reported by pancake.
