Lightweight Java Game Library Code

cleaned up imports

added certificate check
reworked installer to expect a jar with the platform natives inside a jar
now installs into java.io.tmpdir/.lwjglinstall/<timestamp>
uninstaller checks for removed watermark file - tho it never gets removed *grumble*

Implemented variable sized events in preparation of timestamped input events

Removed svn:executable properties on windows java files

Don't delete the generated directories themselves on ant clean-generated, only the source files

Fixed comment

Now that no native side event_queue_t type is used anymore, convert input read() semantics to use normal nio Buffer semantics - that is, move the position when writing events

Fixed comment

Linux: Fix multiple calls of setIcon by creating copies of icon data instead of converting data in-place
