add looser param name matching to DynamicGBeanDelegate

(see also bug 267, and the mailing lists around July 14-16 for more info on this)

This issue is a wrapper for a patch I wrote to make DynamicGBeanDelegate match parameter names more loosely. Around mid-July there were a set of issues around parameters and whether they should be in javabean form, i.e. myParam, or with capital letters, i.e. MyParam. This patch modifies DynamicGBeanDelegate so it will try both before failing. I sent it to the mailing list but I understand that it's easy for things to get lost that way.
