Fix #29 (href link in terms.html doesn't work)

The href link in terms.html was created with the exact string in
.Site.BaseURL for example "www.example.com". If the BaseURL had no slash
at the end, the link was mistakenly created as follows:
"www.example.comtags/term/"

This bug has now been fixed.
