Added the remaining untraslated strings, and also fixed some mistakes in
the translated ones.

Optimized some translations

- The .box-flyout container also needs it's width set upon page load.
- Remove custom height/width upon viewport change (if viewport is small enough).

Compare bare JID of from attr in roster update. @teseo's fix was too specific
and tailored for a misbehaving server (servers shouldn't be sending from the
full JID in a roster push).

- Pending contacts were not aligned to action icons next to them.
- Invite contacts search box went out of bounds on FF

Changed the icon-* selector to apply only to :before (fixes ugly font rendering in FF).

Probably won't make it in next release.

- Round buttons
- Make the head taller
- Wrap name
- Add "view" button for viewing vcard data (needs JS code still).

Other small tweaks as well.

Still needs more work. Needs <fieldset> tags.

The add contact form.
