Update Readme with 4 new patterns
Suppresses warning in isEmpty
Adds tests for ConvertingStringLiterals bugs
Stub for ConvertingStringLiterals

It was more complicated than I thought.
Updates test to deal with double bugs
Adds Log4jBugs
Adds VarArgsBugs
Adds tests for UseVarArgs
Adds tests for Logger Oddities
Add partial tests for HCPBugs

And a bevy of dummy code to prevent actual inclusion of the three or
four jar files for HttpUtils and stuff.
