Improve the exceptions that are thrown by Kotlin-Guiced

Before:

com.google.inject.CreationException: Unable to create injector, see the following errors:

1) A binding to org.jlleitschuh.guice.Interface was already configured at org.jlleitschuh.guice.BinderScope.bind(BinderScope.kt:43).
  at org.jlleitschuh.guice.BinderScope.bind(BinderScope.kt:43)

Now:

com.google.inject.CreationException: Unable to create injector, see the following errors:

1) A binding to org.jlleitschuh.guice.Interface was already configured at org.jlleitschuh.guice.ModuleTest$module binding exceptions provide meaningful exceptions$module$1.invoke(ModuleTest.kt:100).
  at org.jlleitschuh.guice.ModuleTest$module binding exceptions provide meaningful exceptions$module$1.invoke(ModuleTest.kt:104)

This should be -progressive.

I knew it would be good to have you on this PR. Thanks!

-Xprogressive still works, though. The original 1.2.51 (IIRC) release notes said to use -Xprogressive but the Kotlin docs say -progressive. The compiler actually looks for -Xprogressive and will print out a warning to you saying to use -progressive instead.

We aren't at Kotlin 1.3 for this project yet so this can't be done yet, unfortunately.
