C# Class Bloom.Publish.MakePdfUsingGeckofxHtmlToPdfProgram

This wrapper uses the GeckoFxHtmlToPdf program, which we rename to BloomPdfMaker.exe because AVG likes to quarantine it and we want to make it look less scary. Trying to use the component directly leads to obscure bugs, at least on Windows. Isolating the embedded Gecko browser in a separate process appears to at least let us produce the desired PDF files.

The program always seems to fail after it finishes while xulrunner is trying to clean up its COM objects. Running the program standalone reveals this on Linux by printing a scary SIGSEGV message and stack trace. On Windows, it brings up the "The Program Has Stopped Working" dialog which is even scarier. (I have seen the corresponding Linux dialog once after running this program.) However, the problem occurs after the desired output file has been safely written to the disk, and is nicely hidden away from the user by running it via CommandLineRunner.
