Enforce wrapped parameter styling.

[JakeWharton]

Both the JetBrains and Android style guide require

fun foo(
    bar: Bar,
    baz: Baz
) {

when the signature does not fit on one line.

Currently

fun foo(bar: Bar
        baz: Baz) {

is incorrectly marked valid (#26) which is not only incorrect but also encourages the bad practice of horizontally aligning things.

Thank you for the ticket. We'll make sure this is fixed as part of #118.

These changes are included into IndentationRule and ClassAndFunctionHeaderFormatRule.
It's already possible to try them by using snapshot KtLint version - https://github.com/shyiko/ktlint#development
Alternatively, you can include https://github.com/MyDogTom/ktlint-custom-rules . This is just full copy of the IndentationRule and ClassAndFunctionHeaderFormatRule from ktlint:master.

I'm pretty sure, some cases are not handled, but it's almost impossible to find them without feedback from other people.

Fixed in 0.16.0.
