Class and function header format rules, autocorrection for IndentionRule

[MyDogTom]

This PR contains

• new rule ClassAndFunctionHeaderFormatRule that implements Enforce wrapped parameter styling. #130
• autocorrection for IndentionRule (fixes for ktlint not able to add spaces to indentation #116)

Changes from #126 and #118 are included into current PR.

New rule notes

Applies to class definition (eg. primary constructor), secondary constructor and function.
Wrapping is needed in two cases:

• line break is already present
• overall header length exceeds maximum allowed line length

Example

class WithLongClassHeader(parameter1: Int, parameter2: Int, parameter3: Int) {
    constructor(parameter1: Int, parameter2: Int, parameter3: Int) {
    }

    fun withLongDefinition(param1: Int, parameter2: Int, parameter3: Int): String {
        return " "
    }
}

becomes this

class WithLongClassHeader(
    parameter1: Int,
    parameter2: Int,
    parameter3: Int
) {
    constructor(
        parameter1: Int,
        parameter2: Int,
        parameter3: Int
    ) {
    }

    fun withLongDefinition(
        param1: Int,
        parameter2: Int,
        parameter3: Int
    ): String {
        return " "
    }
}
