Duration scale for notes

[dabit]

Currently, the duration scale for a note is seconds.

That is that you can tell banjo to play a specific notes for X seconds.

# Example:
play(c(4)).for(5).at(4)

To be consistent with sheet music, I think this should change to whole, half, quarter, eighth, etc.

play(c(4)).for(:half).at(4)

Or:

play(c(4)).half.at(4)
