Backup a file if necessary

1	backup_file(path, sep = "_", stamp = "%y%m%d")

`path`	A file path.
`sep`	A character to separate the existing file path and the stamp added.
`stamp`	A datestamp (default) and/or timestamp constructed according to this specification (POSIXct) is added to pre-existing files in path.

The stamp is extracted from an existing file's modification time. For details file.mtime(...). If a backup file with the same stamp exists, it is replaced In practical terms this means that by using "%y%m%d" as stamp, only the last backup per day is preserved.

TRUE if succesful, FALSE otherwise.
