Bug 1245916: Add additional browser window scripts to eslint globals. r=felipe

This adds more of the scripts that browser.js relies on and also makes
browser-chrome head files import the browser.js globals.

The MOZ_JSDOWNLOADS block in contentAreaUtils only seems to hide a single
function, I don't see any need to keep hiding that now we're on by default.
