These were taken from Kitware. See http://www.vtk.org/Wiki/Git/Hooks for details on what is checked.
I also added a check that a trac ticket is referenced (which must say 're(fs)', not 'fixes').
In order for these to do anything, developers will need to link to these files from their .git/hooks directory.

Work around windows not freeing up memory straight away causing the ManagedWorkspace performance test to fail. The ifdef will be removed when I check the linux and mac code. Refs #4023

Refs #3806. Added more functionality and matched up signals and slots to do the customisation. The plot now gets updated with a fit and when plotting the guess. One bug remains which is after a fitting is done for the second time the fit curve doesn't change.

For logs as in re #4020 use start_time if found else use run_start, likewise with end_time and run_end.
