When changing an existing Phase 1 entry, the value for "Hash algorithm" will always be shown as "MD5" in the edit-screen, although it is configured to something else (i.e. AES).

CRITICAL: When configuring a Phase 2 tunnel and setting P2 protocol to ESP, this setting is ignored. The GUI will show an empty value for P2 protocol and the ipsec.conf will not contain the required "esp" line.

Upgrade path is not for fiddling with the installed files,
we're importing config.xml, not a full base system.

Also adds a custom user agent to make it easier to filter by version
and moves the crash reporter to a more visible location in the system
category.  :)
