Provide (eventually update) the Landing Page, FAQ and the ToU about b2share

FAQ: https://github.com/SimpleStore/simplestore/wiki/B2SHARE-FAQ

Not sure whether we should just link to this location, or keep a copy in the app itself. I would probably prefer the first option, since it is simple to keep it up-to-date and I don't see any problerms with it.

I will get the Terms of Use too.

You know what should be on the homepage, so just include the FAQ and ToU.

@ukaila, which of these documents should we use? Can we go with the Terms of Use v1.0 for EUDAT B2SHARE Service or is there some important change in the later generic "EUDAT Services Terms of Use" from August?
