[talk-au] Brisbane Cricket Ground

[Warin]

Hi,


I have made some tagging changes to 'The Gabba'


Firstly I think this refers to both the playing and spectating area so 
have placed those tags on the outer way see 
https://www.openstreetmap.org/way/4049692.

The building and playing areas remain but are not named.

I have added a separate way for the cricket pitch and re tagged the AFL 
pitch as AFL only (using australian_football as per OSM requirements)

I think this is correct? Anyone else?
