dotr should exec scripts

Consider script below

// script.scala
def truth(): Int = 42
println(truth())

In Scala, we can use command scala to exec it directly.

$ scala script.scala 
42
$ 

But dotr could not identify bare script, and it complains

$ dotr script.scala 
Error: Could not find or load main class script.scala
$

I have never been able to get ammonite to work in windows, whereas generic scala scripting works just fine, and I use it quite a bit. My preference would be for script syntax to be 100% scalac compatible without special “script-only” syntax, which implies (among other things) that the compiler ignore a hash-bang line, and that scripts be permitted to declare a package. I would be willing to contribute to this, fwiw.

+1 for fixing this. It’s a major pain for us book writers who have most examples in script form.
