Update presentations list on our website

[Carsten Ziegeler <cz...@apache.org>]

Hi,

I just had a look at
http://felix.apache.org/documentation/tutorials-examples-and-presentations/presentations.html

which is pretty outdated, last entry is from January 2011. I'm pretty
sure some of us did great presentations on Felix related topics in the
meantime.

It would really be great if everyone could add their presentations
there, so we get more up to date things included.

I think we should also revert the sorting and list newest first - I can
take care of that.

Regards
Carsten
