UI: wrong values in amarok's theme color scheme

[Martin]

Hi,

since I'm fixing bug 207621 ([0]) right now I had to try out something.
I need user input in the LyricsApplet, so I thought calling KMessageBox() is 
cool - unfortunately it isn't in a Plasma::Applet.

I wanted the applet to be blocked when my KMessageBox is waiting for user 
input.
Unfortunately this isn't possible with KMessageBox so I changed my code to 
showMessage(), which is part of Plasma::Applet.
It provides a nice way to show a message in the applet itself.
(as a small side-note: notmart pushed a fix to block mouse input - see [2])

After porting my code I found that the applet was using wrong colors for the 
message. See here: [1].
Since I wanted this to be fixed I asked in #plasma to find out the reason:
> <notmart> is a problem of the amarok theme colors file

OK... so I went ahead and fixed it in my local branch (sorry, I won't be able 
to push my code today - but I'll do it tomorrow, I promise ;)).
I simply changed the default foreground color to white (since the default 
background color is black)
I'm not sure if this is OK or not, so I need feedback from the UI magicians :)

In my opinion the applet should use values from KDE's color scheme - but I'm 
not sure how to achieve this.

Regards,
Martin
