We like to upgrade MustacheRenderer to use the latest version of the mustache java libraries. It was 0.6 and is now at 0.8. This code looks to be largely rewritten between these versions.
What's shall be tiles' ways of handling support for different upstream versions? eg tiles-request-mustache-1.0 (mustache-0.6) tiles-request-mustache-1.1 (mustache-0.8) or tiles-request-mustache-v0.6-1.0 (mustache-0.6) tiles-request-mustahce-v0.8-1.0 (mustache-0.8) etc etc ~mck
