Offer PPA

Please offer a PPA on e.g. https://launchpad.net for Ubuntu builds. More specialized builds results in 30% increase of benchmarks. For more exact numbers, extra tests have to be done. Builds will be differentiated on version of Ubuntu and on architecture. Added benefit is automated upgrading.

A few things:

1. A '30% increase' in benchmarks is not necessarily going to be a 30% increase in real world performance
2. This is likely very machine specific - while its possible that some machines may gain '30% increase in performance' from a specialise build it is highly doubtful that this is the case for most or even all machines.

That said there is nothing specifically wrong with having it anyway, however we do not have the man power to set up or maintain such a thing.
Contributions are always welcome.

Did some extra testing, real increase on two different machines is ~5%.

I can ask the people who are running PPAs for similar software if they might be interested in adding support for Gulden.

As indication on differences in benchmark: on a quadcore Intel(R) Core(TM) i7 CPU 880 @ 3.07GHz with 12 GB RAM, I got increase from 49.45 kh/s to 103.28 kh/s when building software myself.
