Make string helpers available in all templates

[peteroyle]

Basically I have funnelled all instances of "this.parserContext = context" through the new setParserContext(...) method, during which I "import" the StringUtils class under the alias "render" as per http://mvel.codehaus.org/Programmatic+Imports+for+2.0 . StringUtils was copied and modified from Apache Commons Lang.

Pete. One thing I'm curious about. Can we add this in a way that would allow helpers to be disabled? Say, by Veto'ing a bean?

PS. Sorry for getting back to you so late on this. We had a team meeting last week. What you have looks like very good so far.

Hi Lincoln. I'm trying to get around to this at some stage, thanks for waiting :)

No problem. Actually I had another thought about this. I think it would be better to add this as an extra module that could be included or excluded via Maven (much like Rewrite extensions: http://github.com/ocpsoft/rewrite)
