- Moved guard logic to check functions
 - Functions now return false if they don't hit or are skipped.

 - Broke check_argument into smaller functions
 - Removed warning code duplication
 - Added some one liners to clarify logic

CVE-2013-1854

XML parsing in JRuby

Add rel="no-referrer" to report links

with ActiveRecord::Base.send(:include,  ActiveModel::ForbiddenAttributesProtection)
should fix #288

Don't warn when calling send on user input

Use custom deep_clone for Sexp

slightly faster and probably uses less memory

Make --compare work on output from older versions

should also help with any hash key changes
in the future

We have warnings for use of constantize and for using
send/try/etc with user input for the method name.

Don't show warnings and errors tables if empty
