Round total time of tasks to two decimals
This fixes misrepresentation errors. This occus for example when a task has a length that would be represented using a floating point number that has more than 2 decimals. For example: a task of length 59 minutes (i.e. 0.9833333333333333... hour) is shown on the invoice as having a length of 0.98 hours while in calculations still the unrounded task length is used. When a hourly rate of €100 pe rhour is defined, the invoice will show: 0.98h x €100/h = €98.33. which is confusing and although correct given maximal accurancy, it will obviously not be accepted by book keeping programs.
