Sources bash_profile to fix 'install then run' bug

Also removes code that requires ~/FrameworkBenchmarks download directory (see #578)

This 'bug' happens if some tries to install and then immediately run the
benchmark. The PATH will not be updated yet, and their run stage will
not be able to find any of the necessary binaries. I'm not sure if there
was actually a requirement to log out/back in before running (e.g. a
bash_profile is only sourced on login, so did you have to install then
reboot?!), but this fixes all of those issues as long as the 'source'
command is available
gitignore the results directory

It's unclear to me why this was not already being done. Am I missing
something obvious?!
