Bug fix:
Many thanks to @danehans for noticing that -H (custom headers flag) got broken recently for the command line, the library and its unit tests wasn't affected/was working. Fixed in #150 including regression tests both unit and e2e (webtest).
New feature:
new /debug/pprof/ standard go pprof endpoint for perf analysis of fortio itself as a server (in addition to the already long existing -profile command line argument).
