Several changes on Kontlin. (#2335)

Browse Source 
* kotlin: remove unnecessary semicolons.

Also replace code block language `java` with `kotlin`.

* kotlin: change coding style (Kotlin Reference)

* kotlin: anonymous function -> lambda expression

Anonymous functions and lambda expressions are different in Kotlin.
The code example uses `anonymous function` in the comment,
while the code below is in fact lambda expressions.

* Remove myself from contributors.

Not for trivial changes.

* kotlin: fix a typo.

Thanks @geoffliu to point out this.

* kotlin: change style of default parameter according to Referenec.
