[Tracker] RDF Query and dbus changes

[Jamie McCracken <jamiemcc blueyonder co uk>]

RDF Query is now fully working with search and keyword support too (dbus 
interface has changed too!)

Also a few of the dbus interfaces have been changed to return aas 
instead of a{sv} (the latter preserves the search order whilst hashes 
screw them up)

aas converts to GPtrArray in glib/c with each pointer representing a 
null terminated string array (see tracker-stats.c for how easy this is 
to manipulate)

Also updated all the CLI tools to reflect the new interfaces and 
tracker-query now supports search and keyword params too.
