fix issue 544 -- allow ServletModules to be reused w/o reconstructing new ones.  also fixes a bug where a ServletModule that contained only filters would have run each filter twice if the module was being reused (or three times if it was being used a third time, etc..).  thanks to mathiue.carbou for pointing out the problem.
