AppletLoader: clean up resources (images) when switching to the LWJGL Applet as opposed to when applet is destroyed

AppletLoader: fix bug with LWJGL 2.5 where appletloader crashed if the al_version parameter was used.

AppletLoader - slight tweak to make AppletLoader looks a bit better

OAL patches by Ciardhubh

AppletLoader: slightly more meaningful and friendly error message.

AppletLoader: Remove the boxerrorcolor parameter, there is not much advantage in having different color error message font, its better to have a nice consistent error message then to try scare the user. Also simplifies the AppletLoader api by reducing the number of parameters.

fix: Keyboard focus handling broken when using Display.setParent() applets on Ubunutu (strangly worked on OpenSuse), hopefully should be fixed now.

AppletLoader: fix issue with caching and lzma/pack200 files

Appletloader: fix caching issue with native jars
