Create an automated build and test environment

[NickDraper]

There is an available PC by my desk that should be suitable for this.

We should use LINUX (fedora or enterprise) for now.
We should install a continuous integration environment eg. cruisecontrol or luntbuild.
This will spot checkings to subversion and initiate a build.

The underlying compiler shoud be gcc, but the choice of build tools is flexible at the momnet, but we should aim for the same build mechanism to the available for the developers to use locally as well.

At the end of the build the unit tests need to be performed.

Should we consider SCons?
