This change:
* bolds currently playing song in playlist;
* forces song names in playlist to one line, ellipsize after (...);
* adds jQuery tipsies to get the whole song name, along with the
  artist name, and the album the song is coming from.

No need to split this changeset into three different ones for the sake
of atomicity.

Two first elements were on the priorities / bug list available there:
   http://gitorious.org/owncloud/pages/Home

automatically upgrade the main database on version number increase (doesnt work with sqlite for now)

This adds support for id3v2 tags such as TRACK/TOTAL.

Albums and artists are now ordered by name, song by track number and name.

finish the application store feature so that users can download and install ownCloud apps from our website. there is still a small problem with write permissions. will look into this later

add a formfactor session variable which is autodetected but can also manually overwritten via a get variable.
currently we have:
         * default -> the normal desktop browser interface
         * mobile -> interface for smartphones
         * tablet -> interface for tablets
         * standalone -> the default interface but without header, footer and sidebar. just the application. useful to use just a specific app on the desktop in a standalone window.
In the future we should adapt the userinterface to the specific formfactor.
