builder init command location

[armondhonore]

The current builder init command clones a repo and then sticks it in a hidden directory.

This needs to change so that a builder init git_repo_url works similar to a git clone and create a folder name that matches the git project in the current directory.

We can add a param called builder init -h or --hidden. to keep it in a hidden folder. (IE this flag should use the current code in place)
