Interpolates $MILL_VERSION in ivy imports (#649)

* Interpolates $MILL_VERSION in ivy imports

This overrides the default $ivy magic import by replacing the
`$MILL_VERSION` string with mill's version, in order to facilitate
the loading/update of contrib modules.

Ammonite had to be bumped to 1.6.9

* Removed bloop import

* AmmoniteExit import fix

* Removed repl dep check

* Removed problematic check

* Made ammonite version override-able
