Adding support for the inclusion of Common Platform Enumeration (CPE) of an application in the results.

[Necron3574]

Added 2 functions, analyze_with_cpe(self,Webpage) analyze_with_cpe_and_versions(self,Webpage)

Both of these functions include the CPE (Common Platform Enumeration) of an application in the analysis results. This makes it easier for the user to co-relate the resultant data with various other databases as CPEs are a standardized way of storing application related data.
