Uses the version of SAT4J that ships with Eclipse instead of the one that ships with A4

[GoogleCodeExporter]

Since Sat4j is not shipping with Eclipse since release 3.4, and the solvers are 
improved regularly, it should be better to rely directly on the version of 
Sat4j that ships with Eclipse instead of the one included in A4.

I did a first trial by adding a dependency to org.sat4j.core to the launch 
plugin and by replacing the alloy4.jar file by the one in attachment.

It works if the solver is run locally. It does not work when the solver is run 
on another thread, since we add directly the alloy4.jar in the classpath in the 
class ExecutableCommand.

That feature should prove an improvement for A4E users relying on Sat4j. 
However, it might be a problem for debugging purposes since we would be out of 
sync with official A4 releases.
