Simple time tracking functionality added. Time can be logged at issue or project level.

There's no aggregation reports for now, it's just possible to see all time entries for a project or an issue.
A new "activities" enumeration is added.
Permission for a role to log time must be set (new "Time tracking" section in role permissions screen).
