Allow configuration of asynchronous XHR

Browse Source 
Set less.async and/or less.fileAsync to true before including less.js to
force asynchronous XHR requests to be used.  fileAsync is introduced
as a separate setting to maintain existing semantics, as previously changing
less.async to true would only affect http protocol XHRs.
