MacGui: add "Open Source (Specify Title)" feature
- Optional way to open your source and specify scanning a specific title only ala the cli.
- Should help with sources that tend to crash the macgui while scanning the entire source
- Only available via the file menu as an additional menu item
- All other open source methods are left untouched so to the average user the gui behaves as before.
- In the process eliminated unnecessary -showSourceScanPanel method which simply called -browseSources, now all gui widgets call -browseSources directly
