Don't duplicate networks list on keypair import

In the Launch Instance modal, if the user clicks on the button to import
a keypair, the networks listed in the Networking tab get duplicated.

The import keypair button calls `workflow_init` which in turn calls
`generate_networklist_html` which appended the networks to the list, not
clearing it beforehand.

This makes sure both Selected Networks and Available Networks lists are
emptied before the networks are added.

Sync translation message catalogs with the latest code

In Grizzly branch several strings have been cleaned up since
the release. This commit update message catalog based on the
current code. This allows translators to use the latest ones
and it is good to sync them with the code before the release.

Fixes bug #1207442

Note that this patch is directly posted since message strings
in master are different and will be updated at different timing.
