Added int casts to the time_entry method of the entry class. This class was misbehaving since some of its input came as a string and the comparisons didnt' pan out when they should've (yes, I know, the caller should have ensured that it was sending appropriate data but it made less sense for this method to silently fail so now it doesn't.
Making the modify method of the user class handle changes to an entry's date from the CLI better.
