Contribution lang keys not properly applied on contribution list

Hi,

In the contribution_list and index_body files the HIDDEN lang key doesn't exist (see screenshot below).

The lang key CONTRIB_HIDDEN should be used.

And, in the same idea, the contrib_new and contrib_disabled conditions should use the lang keys CONTRIB_NEW and CONTRIB_DISABLED

But as the "status" label is next to the "contrib type"... this part could be improved, by applying a gender to the status, based on the contrib type (see screenshot below)
