Added function to send string to sbt console (scala repl)
There is a slight bug in sbt:send-region: If the console is not up, it tries to start it. While the console is starting, comint-send-region is called causing it to be dropp
ed. There is no easy way around this so I changed sbt:send-region/string and sbt:paste
-region to require the console to be up
Added global sbt-send-string
console-ready-p should be prefixed by sbt:
Call sbt:send-string and allow to call interactively
