Splash screen support that works. Prettification.
Splash screens based on Swing are NOT okay. On the Pi it will take a good five seconds before this actually displays!
That is, the existing splash screen support only displayed the splash screen after the period during which we want to display the splash screen has largely elapsed...
Java supports the display of a splash screen on startup right away (Before the VM has even been loaded). This commit uses this functionality.
To display the splash screen, java needs to be started as:
java -splash:res/images/splash.png gui.App
This property can be written into the jar. The appropriately modified jar MANIFEST is included in this commit.
Lastly, a slightly less nonpretty splash screen has been added.
