Land #3696, pile of NTP DRDoS 0days

Dr. DoS in da house?
Use peer when writing scanner modules

This fixes the module seen in PR rapid7#3684 to use the peer method at
the beginning of print_* messages, rather than the vhost method at the
end. Doing this tends to make reading the output much easier since it's
more consistent.

Incidentally, this module has an msftidy complaint:

````
--- Checking new and changed module syntax with tools/msftidy.rb ---
modules/auxiliary/scanner/http/ipboard_login.rb - [INFO] Please use
vars_get in send_request_cgi: send_request_cgi({ 'uri' =>
normalize_uri(target_uri.path,
"index.php?app=core&module=global&section=login&do=process"
````

This should be fixed as well, or explained why it's not being honored.
Add link to blog post for NTP modules
No need to escape single quotes in %q{} strigns
Minor pre-release updates with descriptions
add ipboard loginscanner

add loginscanner class for IPBoard with specs
this should replicate the functionality originally written
by Chris Truncer, but move it into a testable, reusable class
Land #3698, release fixes
Merge branch 'master' into aruba-testing
Remove automatic target, couldn't figure out generic payloads.
Add other gdb-supported platforms that run on allowed arches.
refactor the ipboard-login module

now that we have the loginScanner class, we simplify the module
by using the scanner and credcollection classes to handle all
the real work for us
Update bad config error.
auxiliary/scanner/http/soap_xml cleanup

This:

* Corrects Ruby style (most) everywhere
* Uses Rex's sleep, converts to milliseconds -- seconds are too granular
* Moves begin/rescue inside nested verb+noun loop
* Prints errors even if not in verbose mode
* Corrects URI construction when PATH ends with /
Add status message that displays delay between requests
Fix SIP options scanning
