This reverts commit 753731a2.

Didn't afterall worked correctly even thought I thought I tested it.

restore setWindowState and setParent order

    - preserve apect ratio

    - signal-slot connection moved to a better place
    - Art updated in info Panel when artUrl is file://

The bug originates from an implicit conversion to int. This commit
explicitly convert the value to qreal then use qRound to take the nearest
integer.

This restores functionality, that video goes fullscreen on same screen
that vlc player is. For somereason it didn't work correctly when
reparented to QDesktop-screen( num ) widget.

Seems like wget and curl behaves differently: the latter one doesnt
convert %20 to space.

This should fix spurious BadWindow errors from the video displays.

Items are stored twice, once in a tree structure and once in a one-level list.
This patch removes attempt of the playlist_TreeMove() function to move both tree and
one-level instances of an item.

Firstly the reason is that function was not effective in this attempt.
And secondly, the attempt itself doesn't make sense in some cases: you can always
map moves within the tree to moves within one-level, but you can't always do it
the other way around, it is in most cases ambiguous.

Moreover, this patch restricts moves in the tree to within the present parent of the
item being moved. Again, in most cases, moving an item out of its parent or into another
parent is meaningless.

Fix segfault when dropping more then one item onto an item in the left side selector.

Also copy instead of move items when dragging from media library to playlist and the opposite.

The Timer Queue Windows API is not available on WinCE, so this is a
rewrite based on timeSetEvent() and friends. It's not safe yet with
regard to timer deletion.
