Don't use extends keyword for objects

[tandrewnichols]

So extends means "a" is a child of "b" . . . which turns out to be really bad with object literals. We didn't notice till we tried to pass opt.partials in addition to opt.settings.partials and started getting weird circular reference errors, where prototype and constructor were showing up when we dumped the partials.

This pull request adds a real extend method for partials and lambdas.

Also, I was unsure what your process for compiling the coffeescript was. Is there some way that that just happens or do you manually compile?

@vol4ok Is this still active?

Seriously, you're misusing the extends key word. This is not what it's for.
