module override parameter has gone missing

[jimboid]

In older versions of Longbow there used to be a MODULEOVERRIDE parameter that could be optionally provided in application plugin files to alter the default naming of modules from the name of the plugin file to something else. This could be used by users to set the module name if something peculiar had been used.

This should be restated along with tests, as along the line this functionality has disappeared.

This will need adding to dev docs as well.
