Fix for non translated applet names on Remove context menu items.
Currently, the applet name of the **Remove** context menu items of third party
applets aren't translated. This is because the translated string is currently
fetched from Cinnamon's domain and not the third party applet's domain.
Default Cinnamon applets doesn't have this problem.
This commit uses a mechanism similar to the used by the **SpicesAboutDialog**
prototype to try to fetch the correct translated string.
Also, some trailing spaces were removed and some missing semicolons were added.
