Playback options: random all/album, progressive all/album

Hi Peter,

Something I though would be nice to have would be the option to have more than just random pics, for example you could have:
random all (currently the only option)
random album, progressive pictures (from start to finish in each album)
random album, random pictures (shows all pics in album randomly then jumps to the next random album til all albums viewed)
progressive album, progressive pictures
progressive album, random pictures.

There could also be the option of over-riding the settings on a per-album basis e.g. you could set a folder to always display randomly (for a downloaded set of wildlife shots) or always display progressively (for personal photos of a more logically linear sequence like a wedding day).

Cheers, loving your work!

Simon
