RFC: Loading animation for applets

[Omair Majid]

Hi,

The attached patch adds an applet loading animation for IcedTeaPlugin to 
icedtea6.

The patch adds binary files (images). A mercurial bundle is available 
from http://icedtea.classpath.org/~omajid/applet-loading-animation.hg. 
(Use hg unbundle to apply it.)

The main change is adding an animator class to NetxPanel. This 
PluginAppetLoadingAnimator shows the animation in the panel until the 
applet has initialized. To have the animator stop when the applet has 
finished initializing, extra events have been added. All these events 
are now sent by AppletPanel instead of NetxPanel since only AppletPanel 
knows exactly what the state of the applet it.
