Add a simple URLRewriter class to the HTTPClient

logic to modify urls right before they are sent to the server.

Various patches

Patches to move the implementation of virtual destructors to .cpp files
rather than inline in the headers.  Some versions of GCC have issues
with not generating a vftable at all if a virtual function is not
defined in a cpp file.  This can cause dynamic casts to fail and other
sorts of havok.
Checking for srs validity in ExtrudeGeometryFilter.
