#78 Show Predecessor's constraintType in shortand duration/diff

[Anonymous]

I have patched GanttProject such that in its Table view, it shows not just the Predecessor TaskID, but also the ConstraintType (i.e FF,FS,SF,SS) and The difference/Duration. So it is easier for people to see the detail of the Predecessor dependencies in a concise manner directly, with out having to go into Task Properties.

Note that I am not a java programmer, also I am new to GanttProject, so in case If anything is amiss do inform me, so that I can correct it if possible.
