Localization - Unlock Dutch and Finnish translations

These translations are not 100% finished,
but enabling them at least lets people see *some*
of the text in their desired language.

Many thanks to our translators Alf and Ville!
Perspectives - Remove perspectives1.networknotary.org from default notaries

This notary needs to be upgraded to a more stable architecture
before we can update the public key and use it full time.
In the meantime, remove it so the client doesn't waste time
waiting for a response that will never be properly signed.
Localization - Update German descrition and creator in install.rdf

These now match the supplied localization strings
install.rdf - Increase browser max versions
CHANGELOG - Add changes for version 4.4.1
Perspectives - Increment version for 4.4.1 release!
