[NTG-context] ShowThumbs, ShowBookmarks

[Vit Zyka]

Hi Hans and ConTeXters,

please can you add two Named AcrobatReader functions
   ShowThumbs
   ShowBookmarks
useful especially in Presentation (full screen) mode due to missing key 
shortcuts in last Reader versions.
Usage: \goto{thumbs}[ShowThumbs] and \goto{bookmarks}[ShowBookmarks].

Please, can someone add dutch, german, italian, romanian, and french 
translations?

Thanks
Vit
