Don't translate components of the version

When transmitting the Subsurface version string we always want to use the
English terms, not the localized terms.

Fix possible crash attempting network connection

If we didn't get back a JSON encoded string (i.e., if the response
contained no '"') we would access a QList past its boundary.

I'm somewhat hopeful that this is a last second fix for an annoying bug
I've been trying to figure out for a while.

See #514

Revert "Don't translate components of the version"

This reverts commit 6fdbf2069df4f238d7966fef67a31cee5c5eddbb.

That was actually the wrong thing to do, now that I think about it.
Instead we should show the translated version on screen and send a
compact, easy to parse variation of this as the User-Agent header.

Better User Agent for Subsurface

This one is less verbose and very easy to parse. It's guaranteed to have
five components, separated by ':' with no other ':' in the string:

Subsurface:<version>:<PrettyOSName>:<appCpuArch[/osCpuArch]>:<UILang>
