* WIP: first attempt to fix issue-983
* WIP: bugfixes
* Fixed a problem with displaying empty cell dimensions, one warning
* Another fix: don't allow proxy cells to be selected in the instance properties dialog. This creates a confusing behaviour
* Fixed a few flaws in the cell selection scheme on the instance properties dialog.
* Early warning when trying to build a recursive hierarchy.
* Another fix: avoid too much undo in case of errors thrown during 'apply' followed by 'cancel'
* First attempt to fix issue 984
* Fixed issue-983 solution
* Fixed the modification status of PCell parameters for 'apply to all'

Adds variants to size/sized which take a vector instead
of dx, dy and where the mode parameter is optional. So far
anisotropic sizing had to come with a mode argument.
The problem was essentially the "specific path" which got invalid.
The solution is to establish a better criterion for "path validity"
and use for failsafes against invalid paths.
In addition, the path validation has been modified such that a
better choice is made about the remaining path after a cell gets
deleted.
The bug was that while iterating a Region during the gate traversal,
the "select_interacting" was triggering a sort() which changed the
order.
Solution is to pre-sort when iterators are issued also when the
iterator is non-region selecting. This way, plain and region query
iterators can be used together. In addition, the dirty flag scheme
of Cell+Shapes was cleaned up a little for bboxes.
