download script

[tcurdt]

I'd suggest updating the download script in the README to something more along the lines of

PLATFORM=linux # mac or win
URL=`curl -s https://api.github.com/repos/piranha/gostatic/releases | awk '/download_url.*64-'$PLATFORM'/ { gsub(/"/, "", $2); print $2; exit }'`
curl -sL $URL -o gostatic
chmod a+x gostatic

The call to curl was missing a follow redirects and it seems to need a chmod. Also the URL should not have quotes.

At least on mac it works that way.

Thanks!
