references to name in pluggables misleading

[David Lyle]

The term name is used incorrectly and is misleading in the pluggable extensions settings documentation and the enabled files. The value that needs to be specified is the slug not the name. This correction will aid in developers and deployers using the correct value.

Change reference 'name' to 'slug'.
