Bug 31575: Replace Firefox Home (newtab) with about:tor
Avoid loading AboutNewTab in BrowserGlue.jsm in order
to avoid several network requests that we do not need. Besides,
about:newtab will now point to about:blank or about:tor (depending
on browser.newtabpage.enabled) and about:home will point to
about:tor.
