Title: pin lessc to 1.4

Not necessarily what we want to do, but every minor revision of less seems to change how it minifies, which produces churn in supposedly small changes.

At least this should prevent accidental churn, as has recently been committed to master.

My vague plan has been to update less when we switch to bootstrap 3, since that will certainly make big changes to the css product anyway.
