I've refactored the Action and NLA Editor Transform tools to use the Transform System instead of setting up their own transform loops. This should have happened ages ago, but no-one got around to doing so. * There are still a few bugs left to iron out of a few features, but on the whole it should work as well as it used to. These are: the values which get displayed when working with NLA-scaled actions may not all be correct yet; and the Time-Slide tool in the Action Editor is currently kindof broken. * One of the main benefits of this work, is that it is now possible to use Numeric Input during Transforms. * Also, a bug that meant that it was not possible to negatively scale keyframes in the Action Editor has been resolved.
