Relax domain isolation to use TLD instead of FQDN

TorButton 1.9.2.2 in new TorBrowser 4.5, prevents some file host sites from functioning, such as load.to, ziifile.com, and others.

example link: http://www.load.to/StQUxNkHH4/dictionaries.7z

this download link will function in TBB 4.0.8 (with activated)

in TBB 4.5, the same link will only loop back to the file host home page (with activated). the download link will function, however, if TorButton extension is disabled.

maybe caused by the isolation of requests from same URL domain?? (file hosts frequently redirect user after the Download button is clicked. in this example, from http://www.load.to/ to http://s2.load.to)

thanks for attention
