String addition to five-or-more

[Roth Robert <robert roth off gmail com>]

Hi,

I've pushed a bugzilla patch to five-or-more containing translatable theme names. (see https://bugzilla.gnome.org/show_bug.cgi?id=672675 for reference)

The new strings are the theme names, namely:

"balls"

"dots"

"gumball"

"shapes"

Sorry for the late addition, based on discussions we have agreed that it's not strictly an addition of new translatable strings, but rather making untranslatable strings translatable.
The  theme names will appear untranslated in languages not providing a translation, which would be all languages without this patch, with this patch it can be the same or less, 
so the effect is either positive or neutral from a users point of view.

The freeze exceptions were approved by Piotr Drąg, and Michael Catanzaro.

Thank you all for your help with this and I'm sorry for such late addition

Robert
