#485 Bad side effect during colour change of multiple tasks

[jomabrueloe]

I have made up a gantt chart with several main topics
and lots of sub tasks. After this I wanted to change
the color of all sub-topics for a certain main topic
together with this main topic. Therefore I marked all
topics to change, went to "Properties" via the context
menu and changed to the wanted color. As a (very bad)
side effect of this operation ALL topics got the length
of the summarizing main topic. Even after I restored
the original lenght and saved the project, the wrong
times were restored after opening the project again.
The only way I achieved the correct data again was to
cut the sub-topics from the main topic, to restore the
original lengths and to attach the sub-topics to the
main topic again.

I removed multiple task editing in GP 2.0 so this is not an issue anymore.
