Backup file naming (lp:#1500570)
Original report created by xzcvczx (xzcvczx)
Currently backup files are all named completely different based on the
source file
.sch -> .bak
.dcm -> .bck
.kicad_pcb -> .kicad_pcb-bak
to make it more clear which file is a backup of which should there not be a
common suffix, this would also make it safer and easier to add to
.gitignore than it is currently,
