[QGIS-Developer] QEP notification: Rework datum transform handling

[Nyall Dawson]

Hi all,

Following on from discussion at the recent hackfest, please see QEP 100 at

https://github.com/qgis/QGIS-Enhancement-Proposals/issues/100

regarding proposed changes to datum transformation handling within
QGIS. Anyone with interest in how QGIS handles datum transforms
(including the looming introduction of temporal dependant datum
transforms, such as GDA 2020) should read and comment on the proposed
changes.

Timing is tight for this one - but at the same time it's a "3.0 or
never" type change!
