escape branch name

[chenyan-dfinity]

Trying to fetch base from branch joachim/no-word

{ name = "base"
        , repo = "https://github.com/dfinity/motoko-base"
        , version = "joachim/no-word"
        , dependencies = [] : List Text
        }

vessel install fails, maybe due to / in the branch name?

$ vessel install
[INFO] Installing 3 packages
[INFO] Downloading tar-ball: "base"
[WARN] Downloading tar-ball failed, cloning as git repo instead: "base"
Error: No such file or directory (os error 2)

Yeah it's because of the slash. I'm thinking I'd prefer to improve the error message here instead and forbid slashes in version. You can always use a commit hash instead.

Closing since package names and versions are now restricted to letters, numbers, dashes, underscores, and the . character.
