Allow custom change types

[EiyuuZack]

Some projects adapt change types to fit their needs (e.g using present tense Fixes instead of Fixed or adding an Improved change type).

My suggestion for a possible quick solution would be having a .kacl file in $HOME containing a list of change types such as:

Adds
Changes
Breaking Changes
Improves
Fixes
Deprecates
Removes

This file -- if present -- would be read by kacl and overwrite the default change types during lint checks.

I believe this would be a nice feature to have as it provides a good degree of flexibility.

Keep up the awesome work!

Good idea! This project uses https://github.com/oscarotero/keep-a-changelog/ for handling the parsing and manipulating of changelogs, so we'd need to add support for this in there. Currently it's hardcoded here: https://github.com/oscarotero/keep-a-changelog/blob/master/src/Release.js#L17 , but that might be possible to change pretty easily.

and now keep-a-changelog project enables users to add custom types 😺
