Added some ini and image tweaks, as well as new galloping and rearing animations for Applejack, from Bot-chan.
Allow ponies to be dragged whilst asleep, although do not change the current behavior. This also prevents ponies that entering sleep mode getting stuck in the drag state forever.
Fix the sleep all/resume all option to correctly toggle the text.
Changed PonyCollection to update image sizes on a per-pony basis during loading, so that the delay is spread out rather than causing a bulk delay at the end of loading.
Changed interactions to allow each target to individually select any behavior from those listed, subject to group restrictions, and run that.

This affects the 'Any' mode of interaction by relaxing the restriction that all targets considered must be able to start a common behavior. If one did not exist previously the interaction did not run, now instead targets unable to run a behavior simply won't participate.

For interactions with multiple listed behaviors, this allows targets to choose a behavior individually instead of having to start a common behavior. This means interactions can be engineered to allow targets to start different behaviors depending what pony they are, or their current group.
Added some sax transitions for Blues, a make-it-stop animation for Spot and some minor image and ini tweaks from Bot-chan.
Version to 1.49.
