Add filename setting

[CharlieSears]

Allow users to set the output filename with the same restrictions as the command line tool.

Setting the reportFilename parameter will place reportFilename in the reportsDirectory

Command line limitations:

• Cannot specify filename when "ALL" format is selected
• Cannot specify filename when more than one format is selected
• Filename must have an extension: If filename does not contain an extension the command line tool will assume filename is a directory
