    tdf#96370 rework filtering to be aware of WHERE vs HAVING clause

(1) the code was saving PROPERTY_FILTER and PROPERTY_SORT, but loading
PROPERTY_FILTER and PROPERTY_HAVINGCLAUSE
(2) the loading code was not putting the properties into m_xAggregateSet

So I fixed the load/save mismatch, put the properties into the right
location, and added the HAVING property, which meant I needed to do a
version bump.

I will note that this is somewhat of a backwards/forwards compatibility
mess - the commit referenced above added new fields in the middle of the
output stream, which means that older versions of LO will not be able
to properly load forms generated after that commit.
