therefore tracks which have a end point inside a pad, but not necessaryexactly to the pad position are seen as connected, and are no more removed.
Side effect: reconnect to pads option is removed, because it is useless.
TODO: use this algorithm in drag functions.
Minor other fixes
* Set default button on all dialogs that do not already have a defined
default button. The only exception is the EESchema net list dialog
which needs converted over to wxFormBuilder and due to it's design makes
setting the default button in any tab other than the default tab
problematic.
* Fix escape key dialog handling bug in EESchema print post script
dialog.
