[tldoc] Actualization of sk.po

[Karl Berry]

Hi Jan,

    please, find attached an actual version of Slovak .po file.

Thanks, installed.

    I am sorry, I have missed yesterdays deadline. I suppose I will be able to
    prepare the actualization tomorrow morning :(

Please do, if you can.  I suspect that we will be doing at least one
more build even after tonight's (Tuesday).

Thanks,
k
