Made qtiworks.extensions.mathassess default false
WAConfiguration now stores config beans in SvltCtx

This makes the config data available in JSPs, which is nice.
<page/> now prints configured version + contact
Removed some more pointless Eclipse configs
Rendering XSLT now adds QTIWorks version to JS/CSS
Removed old test rendering XSLT
Updated debug examples in light of last commits
Tidied up <script> generation in XSLT
Updated JQuery version in rendering XSLT
Updated JQuery et al in JSP template
Pruned legacy rendering CSS
Rebuilt Eclipse dot files
Created qtiworks-engine-manager module

The standalone stuff will be a lot tidier this way.
Just need to move some code into here to make things work next...
Should have been in HEAD~2
Moved engine 'tools' code into engine-manager mod
Introced @Profile into Spring config

This replaces the confiditonal inclusion of config classes
and seems a bit neater and easier to extend.
QTIWorks manager now has a single entry point

This makes it easier to run; the JAR has its main class set up
so that it's simply a case of executing the JAR and things should
work fine.
Improvements to manager actions:

* Added explicit reimport / update for sample categories
* Added resetUser() to DataDeletionService
Added 'delete user(s)' action to manager
Added usage documentation to manager
