Subject: [PATCH] Bugfix: publicUrl is not used in some urls (#605)

In WMTS the publicUrl path was missed and it was not working properly.
Similar story about wmts.tmpl: the baseUrl is not working properly when
tileserver is hidden behind the proxy with different root path.

* Minor bugfix: make baseUrl always use '/' in the end
