2007-07-13 P. A. Bagyenda <bagyenda@dsmagic.com>
* Introduced ability to filter MT MMS on the VAS side using a generalized module.
* send-mms interface now allows you to push content by specifying a url using content-url CGI param.
* Various minor fixes.
2007-06-21 P. A. Bagyenda <bagyenda@dsmagic.com>
* Better configurability of MM7/SOAP namespace URI and MM7 version.

Optional library to be used for filtering/transforming all content (except
SMIL), while building the MT MMS from a SMIL file. This is useful if say you want
to implement custom filtering/transformation of content (e.g. DRM
wrappers around selected content). Note that only elements
referenced within the returned SMIL are filtered. See
<tt>mmsbox_mt_filter.h</tt> for details. Also see
<tt>mm7-mt-filter-params</tt> config variable in the <a href="#mmsc_vasp">VAS specific
