OSGi Class Loader

[GoogleCodeExporter]

This patch add the ability to create reference to class on other ClassLoader 
(other OSGi bundles for ex.)
A unit test has been written for this ClassFactory. But not for OSGi has it 
requires a working OSGi context. But the test is done on h2spatial OSGi junit 
test.

ObjectDataType of MVStore use Utils.(de)serialize. May be there is a reason for 
this duplicate code, please check it.

When it will be merged, I will merge the master of h2spatial and add it on our 
continuous integration server jenkins.orbisgis.org

Thank you

The patch looks good, I will apply it and test it on my side before committing 
it.

I don't want to blow up the MVStore jar file, that's why I will keep it 
duplicated.

Your code should not rely on the serialization used by the ObjectDataType. If 
it does, then something is wrong: you would use the MVStore directly instead of 
using the MVTableEngine / ValueDataType (which uses Utils.(de)serialize).

Hi, h2 spatial code works without this MVStore diff then you can ignore my diff 
about MVStore.

I found another way to extend h2 through OSGi by using Fragment Bundles. And my 
patch is not a good answer to OSGi issues as a DataBase could not be reopened 
if an OSGi bundle is not found with the same name/version.

I'm sorry but I advise to remove the modification on DbDriverActivator.java 
before someone use it.
