res_geolocation: Allow location parameters on the profile object

Browse Source 
You can now specify the location object's format, location_info,
method, location_source and confidence parameters directly on
a profile object for simple scenarios where the location
information isn't common with any other profiles.  This is
mutually exclusive with setting location_reference on the
profile.

Updated appdocsxml.dtd to allow xi:include in a configObject
element.  This makes it easier to link to complete configOptions
in another object.  This is used to add the above fields to the
profile object without having to maintain the option descriptions
in two places.
