UpdateTimeLeft

What this is

The patch below provides two distinct improvements to the default RT interface (3.4.1):

• Ticket Update interface (/reply, comment/) now contains both Time Worked and Time Left fields, instead of just Time Worked field. This makes it easier to keep Time Left field up to date.
• The above interface is augmented with a javascript event handler that automatically calculates the new value for Time Left when Time Worked is updated. If Time Worked -field is manually changed, the event handler is disabled.

These changes facilitate the following use case:

1. Create ticket with Time Left = 200 minutes
2. Work 100 minutes, half way through, enter Ticket Update interface
   1. Notice how Time Left field contains value 200
   2. Now enter the Time Worked: 100
   3. Move the keyboard focus away from the Time Worked entry (click on another field, use Tab...)
   4. Notice how Time Left is updated to new value: 100 minutes
   5. Jot down a message, Update Ticket
