Some fixes / improvements of the power panic:

Browse source 
1) Fix of an order of SD card function calls on recover: First set position, then restart the print.
2) Some convenience improvements: On panic, the X axis moves to the edge to avoid oozing into the print.
3) On recovery, move Z up if the head is too low to make it easier for the user to clean the print head.
