Ensime seems to be finally dead, as ensime-mode is not longer
available on melpa. The same applies to ob-scala the package
which delivered scala support for org babel.
I have changed the layers default to metals and took care that
ensime is not tried to be installed until it is really selected
as a package.
In addition I have also fixed some smaller issues in the layer
which caused ensime specific settings to be forced even when
metals was selected as a backend.
I have also removed the not longer existing org-babel support
for scala as it requires ob-scala which in turn is based on ensime.
See https://github.com/hvesalai/emacs-scala-mode/issues/155 for details.
a new variable, scala-auto-start-ensime, determines if ensime starts
when a scala file is loaded.
make scala-auto-start-ensime default to t
The current behaviour is to autostart so this will preserve it.
Adding documentation for scala-auto-start-ensime
removed a space

Add a configuration option `scala-use-unicode-arrows` to
the scala layer, which when enabled replaces `->`, `=>`
and `<-` with corresponding unicode characters (Scala
supports unicode arrows natively).
