Allow the filtering of returned module output

When running a module, allow the user to add pipes | to the end of them and run arbitrary filters and module chaining against the output of the original module. For example:
dnsresolve deadbits.org | nmap 'MX' would resolve deadbits.org and then automatically Nmap scan any returned MX records.
or github deadbits.org | filter 'location' would get the Github results for username deadbits and then return the "location" field from those GitHub results

• Create list of compatible module commands that can be executed against the output of the first module
• Create filter command to fetch JSON results keys for display
• Create regex command to allow users to display results of module that matches a provided regex
