fix a compil warning.
CvPcb: fix regressions :
Shows now a void field instead of the dummy footprint name $nonane (whenthere is no footprint selected in netlist).
The active footprint selection changes only if a new component is selected from the component file,
and does not change just when the next component is automatically selected, after a footprint selection.
Speed up delete association and auto associe.
* Factor test for auto save file into base frame class.
* Added auto save feature to Eeschema for saving schematics, addresses
launchpad question 173631.
* Add auto save interval control to Eeschema options dialog.
* Fix problem with subsequent auto saves in last commit.
* 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.
