Patch relevancy checker

[jajajasalu2]

Currently, any patches that the patch-finder finds in the "area of interest" (i.e. in the xpath for a page) are collected without any questions asked. Some or all of the patches that the patch-finder collects may not be related to the given vulnerability. For unrecognized sites/pages, where the xpath is "//body//a", a multitude of patches not in the context of the vulnerability could be collected.

Given the dynamic and uncertain way information is represented on the internet, a way to check the relevancy of a patch for a vulnerability is necessary. This would greatly reduce the number of unrelated patches that are found.
