SNPhylo easybuild script

This is the related scripts for hpcugent/easybuild-easyblocks#394
It includes all the dependent projects. I also have a script for MUSCLE which builds from source but I didn't include it since there is one which just takes the linux64 elf.
@ehiggs: BTW, a very similar easyconfig is close to being merged in #652, so you'll probably end up with a conflict in this PR...
