Allow the user the ability to run a custom script file.
This patch adds a menu item called "Run Custom Script".
When the user selects it, a open-file dialog has the
user select a text file with the custom scripts to run.
This allows for virtually unlimited expandability. All
monitor commands should work with this feature.

To test this patch, save this text "sendkey ctrl-alt-delete"
in a text file. Then run a Windows guest to try out this
feature. That is only a sample of what this patch could do.
Mounting image files, debugging, and saving states are just
a few of the things this patch can help the user to accomplish.
