add prybar-scala (#43)

* install scala 2.13.1 in prybar docker image * start scala repl without args * handle c, e, ps1, q flags * rm commented code * make sure we can at least quit the scala repl * scala 1_plus_1 * scala eval, load file, printing, and ps1 tests * bump timeout to 15 seconds to allow for scala to evaluate first expression
