hotswap native module supports other ClassLoaderPreProcessor

Chris

I have just commited a fix to allow use of the native hotswap module with
a custom ClassLoaderPreProcessor, so that you can use it with your ASM /
Cglib implementation.

Just add a -Daspectwerkz.classloader.clpreprocessor=<impl FQN> as for the
non-native implementation. If not present, it defaults to standard
AspectWerkz bcel one.
If present, the impl has to be in the bootclasspath.
If not found, a stacktrace gets printed, but the VM still starts up.

You will need to build from the latest source from src/native/
It should be backward compatible with AspectWerkz 0.8.x family, even if I
did not checked. You can validate your build using the small
src/native/test and src/native/build/test.bat (adapt for use on non win*).

Enjoy
