Initial implementation for two additional methods in AutomatableModel, AutomationPattern:

These methods are used to fetch the automated value of a model at a given MidiTime
These are still untested but that shouldn't be a problem since they aren't actually used by anything yet... but I'll be doing some testing and bugfixing (if needed) for them later.
These will be an important step in making sampletracks eventually be reliably playable from any position, and more generically, being able to reliably convert MidiTime to real time. Of course they can be useful for other things too (not sure what though, yet).
