The idea is to allow for two properties
These can have some additional text which would be applied to all of the help content so the help can be "branded" without modifying all of the help. Since the help files are plain html files and not setup as any sort of templates, the header will just be appended after the <body> and the footer pre-pended before the </body>.
I have verified with all help documents that this looks okay. If these properties aren't set, nothing is added/replaced.
Additionally a special variable #ResourceBean.name is included to allow the name of the tool as defined in the xml file to be inserted dynamically. It didn't seem like any of the other properties were very useful.
