adding a line for Courier-Bold in the PDFBox_External_Fonts.properties file.

Courier-Bold is one of the Standard 14 fonts, it's not an external font. Also it's a Type 1 font.)

> I have been using PDFBox 1.8.4 to extract text from several different PDF files fine. I use the latest PDFBox app with ExtractText command line. There is one PDF that PDFBox (and iText) fails to extract any text even though I can extract the text with Adobe Reader and also pdftotext.exe part of XPdf. "java -jar pdfbox-app-1.8.4.jar ExtractText Test1.pdf Out.txt". I don't want to have to rely on using pdftotext.exe from a PC since this is part of an automated application. I think the error relates to an unknown font type and having to use the few fonts installed in the jar file. I tried running the API classes and trying to force a font from a certain location but I still got errors. I thought I loaded the font with the loadTTF method but I don't know if that did anything with the font. I would really like to have this working straight from the ExtractText class anyway.
> Here are the errors I am getting. I tried this from both a Windows 7 PC and our IBM i in the PASE environment but I get the same errors. The section starting processEncodedText and on repeats a few times so I just included the first entries.
