support the Scalate template engine as a possible view in Lift so folks can choose to use Scalate templates as an alternative to Lift templates; particularly in cases when developers own the templates (rather than designers) so there's a need for more DRY and easier to hack templates.

a comparison of Scalate and Lift templates are here...

they both have their strengths and weaknesses; kinda depends on your team and requirements as to which approach you'll prefer
