Profiling support for msfconsole boot

Browse Source 
Set METASPLOIT_FRAMEWORK_PROFILE=true in the environment.  Run
`./msfconsole -q -x exit`.  A pdf will be saved to
tmp/profiles/msfconsole/YYYYMMDDHHMMSS.pdf with the call graph with
numbers being in 100 samples per second.  The pdf is automatically
opened with `open`.
