Updates to ScreenShot, FileWatcher and other plugins

[patrick]

We have updated many of our plugins to better support different versions of Servoy and have added new features to a few components.

The ScreenShot plugin 2.0 works around a bug on the Mac with several displays and adds support for displays in general. Screenshots can be taken for each display etc.

The FileWatcher plugin version 1.3 adds a new and more robust mechanism to figure out if a file is open.

All of our components have been updated internally to better support Servoy 5.2 and future versions.
