Add project alias to distinguish projects with the same name but in different path

[bigshans]

I have two projects with the same name located in the different path. Now when I call Project to add a project, it will overwrites the previous one. The feature of alias will help to slove this problem.

Thanks.
This is a bug introduced by a8fbb53. Projects with the same name on different paths are actually added. But they are hidden if they have the same name to the current project.

I've changed name to fullpath to fix this issue by 50a95c7. Please update and try.

The bug is fixed, thanks!
