[Gluster-infra] Gluster.org website revamp

[Tuomas Kuosmanen]

Hello fine folks :-)

I pushed some further updates to http://glustermm-tigert.rhcloud.com/
for testing, still having them in my local branch for now.

Mostly fixes for mobile browser layout (try with ipad and phones) and
put stuff in the footer, also comments welcome about what we could have 
there, havent given it very much overall review yet.
