[Features Request] Various Improvements

[VoidSec]

Hi, I've "compiled" a list of IMHO useful improvements for the plugin. I'd also like to offer my support in coding some of them (namely #1, #4 and #5) for which I'll try to make PRs in the upcoming days.

Quality of life:

• [x] #7
• [x] #8
• [x] Exclude from results items that have an empty "FoundIn" columns

Missing Rules:

• [x] #9

Windows Rules:

• [ ] Add "dangerous" Windows API/Windows-related vulnerabilities

PS: feel free to split them into specific issues we can address or rework any of those items. :)
