[Imports] Proposed import: Geelong building data

Unfortunately there's not a wealth of GPS traces in the area, but Andrew
Geeson (http://www.openstreetmap.org/user/geesona) is both a local and
fairly active mapper who is already populating a lot of buildings in the
area.

Part of the plan to ensure there is an accurate data set is to collect a
number of GPS traces, and focus on areas known to Andrew first.

While there is an offset, it's quite hard to decide on what's most accurate
- the LIDAR + photogrammetry that has taken place in the production of the
original data is presumably verified by the local government using it to
physically inspect areas.
I'd probably trust this more than bing, simply because it's more important
for the local government to have accurate data than it is for a US based
mapping division.
