This commit breaks LESS running in browsers. The root objects on `tree.Import`s are now sometimes no longer Rulesets, but `tree.Import.prototype.eval` assumes that they are (well, it assumes that `this.root.rules` exists and is an array). I haven’t isolated exactly which piece of code is causing this problem, but the issue is introduced in this commit.
