Description

If I set:
set('keep_releases', 3);

then there is four release folders and additionally every second deploy the wrong folder is removed.

For example:

1. in releases folder there are 3,4,5,6 folders
2. I do deploy
3. in release folder there is now 3,5,6,7 folders
4. I do deploy
5. in release folder there is now 5,6,7,8 folders
6. I do deploy
7. in release folder there is now 5,7,8,9 folders

Counting is wrong, will fix it. But sorting based on mtime, so if you touch something in old release - order are about to change.

I think solution is only to sort alphabetically using sort php func.
