I have added a "Reload File" action to the scripter plugin. This allows you to reload the currently active file when it has been edited outside the scripter interface.
Reasoning:
I was preparing a python script. I realised that I may want to use a text editor e.g. Kate to edit my py script externally or a python IDE. I then noticed that Scripter does not detect any file changes. Currently to reload file contents I had to either close and open the file using Scripter or exit the Scripter window and relaunch it from Tools->Scripts->Scripter.
Both of these methods are slow. So I added a "Reload File" feature so a user can just press Alt+R or use the menu entry to load the external changes back into Scripter.
