Disable SigKit and enable WARP by default

[emesare]

Right now on 4.2 dev we have SigKit as the function matching toolkit and and experimental WARP function matching toolkit. The intention is to disable SigKit and run just the WARP integration. Before this can be done we need to iron out the matching issues.

• Function adjacency on identical function GUID's creates a cascading set of false positives.
• Types with only GUID's are stored in the binary view.
• Certain functions in msvcrt are not being matched due to mismatching basic blocks at the time of GUID creation.
• Users should be able to blacklist WARP signatures
