New Pootle UI

[sophi]

Hi all,

First thanks to Andras and the dev team of Pootle for this new version

There is just one thing that is misleading for me. When you want to
upload a file, the label of the upload link is 'Upload (.zip)' when you
can also upload .po files.

Other than that, everything is ok for me, again thanks for you work!

Kind regards
Sophie
