* Updated tag library to JSP 1.2 specification.

* Added support for storing GraphContext in sessions, so that graph web app can  be deployed in a cluster. This is done by setting the  "org.faceless.graph2.UseSession" context-parameter to "true".

* Added support for new Java 1.6 java.awt.LinearGradientPaint to XML. This is  done by setting the Color attribute to match the format  'gradient(c1,v1, c2,v2, [c3,v3, ...])', where 'cn' is a Color and 'vn' is the  value where that color should be set. See "xml/linearexample.java" and  "LinearGradientExample.java" in the examples folder.

* Added new "svg-sniff" format which will create SVG graphs in a manner that  works with IE8.

* Added hsv() (aka hsb) to the ways of specifying a color in the XML.

* Correctly set external fonts in graphs created by the Report Generator.

* Use of pattern() colors in PDF graphs now follow the "pattern" format defined  in the Report Generator.

* Fixed handling of "dpi" XML attribute.

* Don't generate client-side JavaScript from the XML graphs unless required.

* Changed AreaSeries to paint gradients vertically, rather than diagonally.

* Change DateAxis so that it respects user set timezone even when the format  doesn't contain time information.

* The "key" now respects font attributes under all circumstances.
