locked object can be selected by the DRC operation

[madGambol]

For some objects, a DRC operation will select locked objects.

"Unselect All" won't deselect them.

Selecting another object and moving it will move locked objects selected by the DRC operation.

I recently fixed a bug that would leave silk lines selected after a DRC. The DRC now leaves all flags in the state they were prior to executing. In the gtkhid at least, where the DRC finds all errors, then reports them as a list.

In the lesstif hid, it works one at a time. So, it's possible that if a locked object was part of a violation, it will be selected. If the user cancels the DRC, it will leave the object selected, however, it does not allow the locked object to be moved.

It is still the case that "unselect all" does not unselect the selected locked object. So, part of this bug is still valid.

After merging my home/cparker/drc_updates branch, the lesstif HID will no longer use the selected flag for displaying DRC violations. So, this bug will no longer be relevant.

I would like at some point to allow locked objects to be unselected, but this is currently not a trivial fix. Eventually, I plan to overhaul things in a way that will make this much easier, and will implement it then.
