Add option to include startTime in event note filename

[AnnaKornfeldSimpson]

Including the startTime with the date in the file name of each event would be really useful for sorting through the folder explorer view when days have multiple events. Could you please make this option available?

I think this would require adding ${event.startTime.replace(':','')} between the date and the title in the two spots below. (The replace is necessary because : are not allowed in filenames.)

(Noticed while looking at the code: I believe that the second spot, L12, has an extra ) at the end of the line.)

Thank you for all your work on this very useful plugin!
