Fix reference - Listeners not working

[ojhernandezc]

For use listeners add implementation "org.jetbrains.anko:anko-sdk25-listeners:0.10.8" in build.gradle

I've found that none of my listeners will fire in a release build, although they work as expected from the debugger. Adding implementation "org.jetbrains.anko:anko-sdk25-listeners:0.10.8" doesn't seem to fix it.

I guess it's back to nasty old XML layouts... Shame.
