skinning elements for 'not loved' icons and wavebar

[jistme]

It would be nice to have skinning/image elements for:

- 'not loved icon' sidepanel player
- 'not loved icon' pop-up panel
- color elements for the wavebar(s)

[Steven]

this has support for a wavebar

<element id="Player.Wavebar" fg="250,10,100" fg2="100,200,9" />
if you also put in a bg value it will fill the background rectangle with that colour
