Change default compiler to oyejorge/less.php

[pravdomil]

Since the https://github.com/oyejorge/less.php compiler is more up to date and it's offical port for Less, I would recommend to use like a default one.

For example it supports passing ruleset into mixins:

.mixin( { a: b; } );

And also http://lesscss.org/functions/#misc-functions-data-uri
