Support require('less').render(str, options)

[tj]

I have been trying to get all the SSJS rendering
engines to follow this convention so that they can
work with Express out of the box.

options like "locals", "context" etc do not really
apply here but thats the signature anyways

Just added it, but it takes a callback too, as the parsing is async:

whats async about it if another framework handles the IO ? (didnt look at your implementation yet)

[cloudhead]

The async part is file I/O, when evaluating @import directives
