Review request for KDE Base Apps.


Repository: libksysguard


Description
-------

This will add a new column "Relative Start Time" which shows how much time has elapsed since the process was started.

Some details:
- add new heading with default location between "Shared Memory" and "Command" and not visible by default
- define What's this
- define Tooltip
- define sorting
- add class TimeUtil with methods:
  - systemUptimeSeconds
  - systemUptimeAbsolute
  - secondsToHumanString1 (for this one a unit test was added, see chronotest.cpp)

This code reformatting goes in separate commits:
- ProcessModel.cpp: reformat code: consistent number of linebreaks between method definitions (1 blank line)
- ProcessModel.h: reformat code: split long enum line into separte lines for better diffing

Side note on sorting:
I was wondering if the sorting of the PID column is exactly the same as with the new "Relative Start Time" column. When testing on my computer it was. But according to this post one cannot generally assume that sorting by PID will reflect the relative start order of the processes: http://stackoverflow.com/questions/822797/about-the-pid-of-the-process

Testing
-------

Run ksysguard, show new column, sort in both directions.

Minor issue: as the seconds pass the values in the new column will not be updated automatically unless there is some user interaction (like mouse hovering/moving or sorting).


Thanks,

Gregor Mi
