Rehab FAQs

I've added a new page of frequently asked questions to the top bar.  This replaces the rehab horses tab, which was proving too time-consuming to keep up-to-date, and as news on rehab horses can also be found within the main blog, I thought a FAQs page was a better use of space.

The introductory paragraph is the same, and the FAQs are a bit further down, so do have a read through.  I've tried to cover the queries I often get from people wondering whether to send their horses here and if you've got an idea for a question which isn't yet covered, please suggest it and I will try to include your question and my answer :-)
