The reference macro is conflicting with other extension Numbered Reference Macro

It's possible to install both "Numbered Reference Macro" and "Reference Macro for the Numbered Content Applications" extension at the same time, but that does not make much sense since they both share the same macro name.

Ideally, both macro should have a common extension feature (using xwiki.extension.features) in the extension descriptor, which feature depends on what are the differences. I don't know those macros very well, but this reference macro seems to have more or less the same parameters as the other one but is more recent, so it should probably simply have the other extension id as feature (but associated with a specific version since both extension don't have the same versionning).
