Dive site management and taxonomy test

[Davide DB]

Taxonomy BUG #1

tags are not updated if I change tags format form preferences: the new
format is applied only to dive sites without tags.
If a dive site has already some taxonomy applied this is not updated
via the globe button :)

PS

I'm playing with taxonomy and I get really strange results... I know,
it depends on the service we use. I will check there manually.
