soapui 1.5 beta2 available

This is the second beta for soapui 1.5, it introduces no new major functionality but:

* fixes a large number of internal issues and adds some improvements in the area of LoadTest timings, etc.
* includes most of the updated documentation both on the site and in the distributions
* includes the first 1.5 beta of the maven-plugin

As always huge thanks for all feedback and encouragement! Keep it coming :-)
