Make XHProf easier for me to use with other users
Summary: Ideally there should be a "send epriestley this profile" button but this is a reasonable step forward. Add a "download .xhprof profile" button to profiles, since walking through these things remotely is pretty awkward. Also expand "Excl" and "Incl" acronyms.
Test Plan: Clicked download button.
