 Add support for relative submodules

Currently there is no support for submodules where the url starts with ./ or ../, it will fail with an Routing Error.
This is required is you don't want to force a submodule to ssh or http usage.

For a given Repository __http://server/group/root.git__

[submodule "sub1"]
	path = sub1
	url = ../submodule.git

Wrong: http://server/group/ __root__ /submodule.git
Correct: http://server/group/submodule.git

---

[submodule "sub2"]
	path = sub2
	url = ../../any/submodule.git

Wrong: http://server/ __group/any__ /submodule.git
Corrent: http://server/any/submodule.git
