Implementation with TracHoursPlugin

[V.Cejka@…]

Althrough TracHoursPlugin should be supported, tracked time was not stored to its database table. I'm not used to work in Python, so my patch is not done the best, however I fixed it for myself by slight modification of manager.py. In stop_work procedure there is section used to store time in TimingAndEstimationPlugin, I added code for TracHoursPlugin there also:

    if plugtne:
        tckt['hours'] = hours     
    if plughrs:
        trachours = TracHoursPlugin(self.env)
        trachours.add_ticket_hours(active['ticket'], self.authname, delta * 60)
    self.save_ticket(tckt, message)
    message = ''

Of course, also

from trachours.hours import TracHoursPlugin

should be added, however this implies dependency on Plugin not installed by all users. Because I do not know Python, I do not know proper way of dealing with it.

Either way, thanks for the Plugin!
