v1.2

Changelog:

• In version v1.0 the configuration parameter deep has been substituted with depth. The deep parameter stored in old configuration files was ignored. Now old configuration files are supported as well.

• Fix octal integer handling:
  In the previous versions we use to represent an octal number with a 0-prefix. Since python3 has migrated to 0o-prefix rapresentation, we decided to switch to our custom simple representation: the octal number should be a simple 3 digits number.
  So for example if in the previous version you were using 0660 as value for the fmode parameter, now you can also use 660.

  In any case we keep support for 0-prefix and 0o-prefix as well, thus you don't need to change
  anything before the upgrade.

• Added tests to source package (thanks @boyska )
