Add solution hint for deprecated ignore-kde-structure
Regarding #62 (closed), this MR fixes the initial build setup. Adds the new keyword
directory-layout to the vim script,
and most importantly adds a solutions hint to the deprecated-setting warning.
However, this change further convolutes the terminal... but might make it more clear to the user how to fix it.
Since I am not very familiar with perl, nor have any seniority on this repo... please have a look at these changes.
