I would like to submit a query filter for each agent type:

https://groups.google.com/forum/#!searchin/recastnavigation/dtQueryFilter|sort:relevance|spell:false/recastnavigation/t-rFg2Ku9IY/PJNNkCjARccJ

Search on
queryFilterType and m_filters to see the changes.

Also in this code there are bugfixes, that have already been submitted
as issues. They can be ignored.
