adds py extension to script
adds example script and .ignore for future scripts
Changes from simple snapshot to rotation scheme
(daily, weekly, monthly, yearly)
increases amount of weekly snapshots to keep to 5 (since that is the monthly limit)
Fixes nasty bug in path determination.

On some python systems os.path.expanduser() does not handle
/ and \ correctly if there is a line end/feed difference
(tested on busybox system). Fixed by stripping all stuff from
the input.
adds ssh support for the mv command
Removes creating backup dirs for remote hosts
Adds a warning that they should be manually
created when using remote host.
