Add "delete objects out of the log list" feature

[Matthias Burkhardt]

If the user wants to delete several points and items and newly loaded the pattern file, the back button is not functional any more. Now she/he has to look into the chronic/log to see the last actions, as older actions with dependencies are not deletable. It is possible to select the last action (very good!) in the log, but to delete the object, the user has to move the mouse, activate the main window and select the object again to delete it. It would be better if the user could delete the last object directly in the log list. Left mouse Button=select; right mouse button=delete

So deletion of several objects would be much faster.

of course (not knowing how complex the coding would be for this but..) it would be helpful if in deleting points N - N-"5" you could select point N-5 and have the points N-6 through N selected also (maybe with a dialog box popping up stating "Warning Multiple Points selected ARE YOU SURE YOU WANT TO DELETE? [yes] [no])

Good idea, it is easy to implement.

You speak right now about issue #186: Smart deletion.

Main problem is formulas and internal variables like Line_A_A1. Program need parse all formulas and analyze all such variable for making whole dependence graph.
