Corrected error in user manual. WMS Basics section incorrectly specifies
WMS version 1.1.1 instead of 1.3.0 in example request. (Example shows
different axis order between 1.1.1 and 1.3, but passes version 1.1.1
in both requests.)
added scripting web UI docs, added docs for WFS TX and Filter Function hooks
