[Translators] Update for Slovak translation of VLC

[Marián Hikaník]

Hello, 
thank you for merging of my last update for SK translation for VLC and now I prepared now the newer version. PO file was downloaded from:
http://git.videolan.org/gitweb.cgi?p=vlc.git;a=tree;f=po
and contains 5420 strings. All strings are translated now, you can download this new po file on www.mojepreklady.net/download/po-sk-5420.zip
Please upload this file to your server. 

Thank you for your collaboration. Best regards,
