[GEOT-4239] Avoid hard-coding batch size for oracle JDBC datastores, patch by David Winslow
Fixed app-schema filtering

MappingFeatureIteratorFactory.getInstance was changing the filter of the query that was passed in and as a result a given FeatureCollection would only work correctly once.  This change makes a copy of the passed in query before updating it.
[GEOT-4243] Resampler2D might fail to invert axis order
GEOT-4233 temporary work around
A couple things to avoid the infamous SDE 'DATABASE LEVEL ERROR OCCURRED' errors when computing bounds and result count:
- do not qualify attribute names for the where clause, it doesn't works in all cases
- include  both the row id and the geometry columns in the list of attributes for the stats query
- use of FilteringFeatureReader in the DataStore instead of lying about the unsupported filter. That makes the geometry filters work but break other tests
Release won't work because running clean alone still requires the gt2 maven plugins to be already available, also build with -Dall, Jody was looking for some of the modules in there and the old release guide was building with -Dall anyways
Fix README links to refer to the stable docs
[GEOT-4005] modified method internalIssueRequest to log requested URLs
ensuring that parser delegates rinheirent namespace prefix mappings, see GEOS-5298
Correcting illegal argument exception message.

Backport of pull request #18.
Changed parameter names with blank spaces. This can cause problems when reusing them at an upper level to call processes (for instance, when using them as an argument name)
Removed AggregationFunction enum at UniqueProcess (probably left there unintentionally)
