fixed bug with hairpins ending on dynamics; hairpins now have a velocity change of 0 by default, which causes it to use the next dynamic as end velocity (unless it is contrary to the direction of the change)
fix #34421: add macros for last modified time and date

and fix the case when the creationDate meta tag is empty.
fixed crescendo/decrescendo tests since default velochange is now 0 instead of 10; VELO_CHANGE is now saved with writeProperty(); fixed edge case with a final hairpin not followed by a dynamic
