temporal: a guess at how to use BBT markers from within TempoMap::paste()

Browse Source 
Basically, if the paste position is not zero and not on a bar line, we will a BBT marker there,
using the existing tempo & meter at that position before the paste.

If the end of the paste is not on a bar line, we will place a BBT marker there,
using the tempo & meter that existed before the paste.

TempoMap::paste() now also accepts an optional final argument that if provided is
used to name the BBT markers, if they are created
