ok I have no added the following 2 new component impls:
* WebAppVelocityConfiguration
* WebAppVelocityEngine
However it's not enough since DefaultVelocityEngine.createVelocityEngine() does a
component lookup on VelocityEngine and we need a way for it to look up with a passed hint.
I'm proposing to modify the current VelocityFactory API from:
    VelocityEngine createVelocityEngine(String key, Properties properties) throws
XWikiVelocityException;
to:
    VelocityEngine createVelocityEngine(String key, Properties properties, String
engineType) throws XWikiVelocityException;
where engineType is the hint corresponding to the engine to look up.
Then DefaultVelocityManager can call VelocityFactory, passing the "webapp" hint
to createVelocityEngine.
WDYT?
Thanks

  Just a heads up of what I'm working on right now:
cleaning up xwiki-velocity dependencies.
 I'm going to split it into several submodules:
 * xwiki-velocity-management (or xwiki-velocity-jmx)
 * xwiki-velocity-default
 * xwiki-velocity-webapp (implementation of VelocityEngine and VelocityConfiguration with
hint = "webapp",  this is to use use velocity with the WebappResourceLoader
loading templates from the webapp's root dir)
