html5 video tag support

[j]

commit plumi video template with video tag. commit changes to indytube to read ffmpeg2theora options

make sure that it works on all browsers with video tag support: known open issue:

without h264 version, safari does not work if XiphQt? is not installed

provide better h264 version, current encode is to big and seams to only start once fully downloaded. (verify with safari)

Known to work right now with Ogg Theora version:

Firefox 3.5 Google Chrome Safari with XiphQt? or Perian

[and]

This is working in Plumi 3.0 and no real need to make it work in 0.2.4.
