remove ability to trust not validated macro signatures in high security
Giving the user the option to determine if they should trust an
invalid signature in HIGH macro security doesn't make sense.
CommonName of the signature is the most prominent feature presented
and the CommonName of a certificate can be easily forged for an
invalid signature, tricking the user into accepting an invalid
signature.
in the HIGH macro security setting only show the pop-up to
enable/disable signed macro if the certificate signature can be
validated.
Additionally present a ViewSignatures button in the Macro Disabled
infobar, so that the user can inspect what are the invalid signatures
and why (wihtout the ability of enabling macros).
