Support for typelevel scala > 2.11.

[lJoublanc]

The Installer script has instructions to set up typelevel scala. However, since about version 2.12, the typelevel compiler artifacts have a suffix -bin-typelevel-n where n is the language feature number. This means coursier fails to fetch the packages.

This is easy to fix by tweaking the script. However, then the kernel fails to load:

Not certain if this is a problem with upstream ammonite, or jupyter-kernel.

Note that it's trying to fetch non-exiting ammonite artifacts - it's tagged on the -bin-typelevel-4 suffix to the package names. I can't find where this is inferred in the code.

[lJoublanc]

I suspect this is because the ammonite-xx dependencies have a CrossBuild.full qualifier. Will try changing this to CrossBuild.patch, to see if that works. On a side-note it seems that SBT 13.x artifacts have been removed from maven central just today.

[lJoublanc]

The above change didn't work. :( any help appreciated.
