Add directive @reference "<lib.less>"

[ruslanurban]

Use of @Refence directive would be similar to @import directive, with the exception that only the contents of the current and @import files will occur in the output.

This will allow for splitting less output into multiple files. (e.g. site and area-specific style sheets).

This will also help to overcome IE6-9 css selector limit (http://blogs.msdn.com/b/ieinternals/archive/2011/05/14/internet-explorer-stylesheet-rule-selector-import-sheet-limit-maximum.aspx), and this is the main reason for this request. Our project uses 2 frameworks (Bootstrap 3 and KendoUI), and our combined site css contains 4713 selectors, which exceeds IE6-9 limit. And, site.less uses variables and mixins from both frameworks. The @reference directive would allow us to split the output into multiple files which is problematic with the current implementation of LESS.
