Description

This is an extension of the PR #471. As that PR has not been merged yet, I do not expect this to be merged, but I still want to give you a chance to see this.

The main addition to the previous PR is that multiple stacks in one Repository can now be used and are correctly shown in Dockge. This is not perfect and there are a lot of improvements to be made. However, this works for me. If anyone finds any bugs I will happily fix them. :)

How does this work?

With this, every folder inside the StacksDir is scanned up to a maximum depth of 3 (This should probably be a setting) for a compose.yml. The Stack names are now not just the parent folder, but everything up until the StacksDir. This means that the name attribute cannot really be used (but before it couldn't either).

Also, I rebased onto the current master.
