Version 0.17 - Be able to handle a larger project
QT has been added as a sample project to show case the handling of large projects. QT has thousands of commits with hundreds of different developers.

• Fix URL path for different projects
• Change title for current project.
• Add in Version name in title.
• Be able to set properties file by passing in system variable.
• For unit tests only statically import.
• Grab screen shots for projects and have them show up in GIT hub as examples.
• Remove passing in arguments and base only on property file.
• Legend becomes ridiculously large for large projects and dominates the screen. Maybe a smaller scrollable window is needed? No possible with jFreechart instead don't show the table for commits greater then 10.
• Chart and Panel are fixed in size, they should be dynamic
