မော်ဂျူး:Proofreadpage index template

Documentation for this module may be created at မော်ဂျူး:Proofreadpage index template/doc

--[=[
This is a module to implement logic for [[MediaWiki:Proofreadpage index template]]

It doesn't do everything yet, but over time it can accrete functions from
the template, which will become simpler and simpler until it's just an invoke.

Implemented so far:
 * Status categorisation and field
 * Some auxiliary data fields
