i have made a simple addon again, which allows you to quickly open source files of addons with a single or with multiple files with a click of a button directly from the Addons page under User Preferences.
Just install and activate the addon as usual and you can also set optionally an external text editor as preference. If you leave it blank, the source files will be opened in blenders scripting view.
After enabling the addon you should see following:
This “Edit Source” button will be added to all addons automatically and will open the sources of this particular addon when clicked.

Edit: slight update by adding a “Use External Editor” checkbox,
so you dont always have to clear out the editor path if you want to use the internal editor in the mean time.
