First bits of work for a MarkupTemplateEngine
Add support for multiple types of includes (groovy, escaped, unescaped)
Added support for template configuration
Added support for new lines and avoid use of "mkp."
Support for tags which have the same name as a macro
Reworked to get rid of StreamingMarkupBuilder
   * templates are statically compiled
   * unresolved methods/properties are executed in mixed mode
Small performance improvements
Fixed nested builder calls not being directly wired to methodMissing
Fixed nested methodMissing calls inside resolved closures not being statically linked
Fixed broken tests
Support for helper methods in bindign
Support for automatic escaping
   * if autoEscape flag is on, then $foo will automatically be escaped unless we use the direct ${model.foo} syntax
Add direct call to getModel() for faster resolution
For direct, unescaped access to model, create an "unescaped" alias for "model"
Added support for a type checked model
Make sure templates included in type checked mode are also type checked
Add auto-indent feature
Add support for automatic new lines
Fixed build of Groovy template module
Added support for a custom base template class
