#152 wicket 1.4.7: support/use wicket 1.4.7 instead of 1.3.1

[Francis ANDRE]

Hi

I am using another software package build on top of wicket and I would like to integrate both within a single war, but JTrac is using wicket 1.3.1 while my application is using 1.4.7. Could you upgrade the code base of JTrac to use wicket 1.4.7?
