String addition to file-roller

[Carlos Soriano <csoriano protonmail com>]

Hello translation team,

I just pushed some string additions to file roller and will make the .91 release now.

The string is the nautilus extension, and they are:

Extract Here

Extract the selected archive to the current position

Extract To...

Extract the selected archive

Compress...

Create a compressed archive with the selected objects

Hope it's fine being officially in string freeze but without the .91 release done in file-roller (I know it's not an excuse, but wanted to push as soon as possible to not be so far from official string freeze).

Best regards,

Carlos Soriano
