Firstly, it doesn't look like there's a subcomponent defined for the "Next Build
Number" plugin, so I've just assigned this to "plugin".

There is a case when a user has launched a build (either manually or scheduled)
and it needs to be deleted and the same (or similar) build run again. This
happens when there is some kind of network or power outage unrelated to the
source code.

In this case, I'm still having to edit the "nextBuildNumber" files on the disk
and reload the configuration from disk. This is quite annoying because it
doesn't work well when builds are running, so you must have some downtime.

To keep a long story short, it would be nice to be able to decrement the build
number using the "Next Build Number" plugin as this plugin is awesome and has
saved me a lot of time!!!
