Introduce toProtoString to returns the ASCII format, instead of toString

To keep the original behavior where toString returns the ASCII format,
use scalapb.gen(asciiFormatToString=true) if using sbt-protoc, or
pass the generator parameter `ascii_format_to_string` if using ScalaPBC.

Fix #235

@@ -14,6 +14,9 @@ Changes:
   type classes that deal with Oneofs.
 - Add support for Scala annotations on field-level, and companion object level.
 - It is now possible to specify additional traits for oneofs.
+- #235: toString is now not overridden by ScalaPB and does not generate the
+  default TextFormat. To get the text format, use toProtoString. See issue #235
+  for how to achieve a backwards-compatible behavior.
