Add an option to disable or ignore log entries

My Fiddler log is usually filled with thousands of ClientHello warnings. It's a burden for me to read through the log with all those messages. For example:

23:42:42:4843 HTTPSLint> Warning: ClientHello record was 508 bytes long. Some servers have problems with ClientHello's greater than 255 bytes. https://github.com/ssllabs/research/wiki/Long-Handshake-Intolerance

I discussed this with Eric Lawrence in the Fiddler Groups thread HTTPSLint> Warning: ClientHello record was xxx bytes long and he had a few suggestions:

Stop logging these entirely, or maybe log them only when the handshake is between 255 and 512 bytes (https://cs.chromium.org/chromium/src/third_party/boringssl/src/ssl/ssl_test.cc?l=1082&rcl=9f0e7cb314ae64234b928fd379381ae9760a9a5f). I think today the warning in Fiddler is simply >255 bytes. But we should probably get rid of this logging entirely, as the buggy server appliances are probably out of the market at this point. Although maybe show a warning at >767 bytes as a) that's huge, and b) we found that there's a server called Gatling that fails on handshakes that big.
Extend the existing interfaces related to Log handling to allow an extension to "eat" messages so that they don't end up in the log.
Extend the Log tab to make use of that new interface to have an "Ignore regex match" box.
