Description

This PR extracts Detekt's config into a new custom plugin PillarboxDetektPlugin. It also strips the detekt.yml file of all the default values to keep only the custom configuration that we need.
This means that we now have a bunch of new activated rules. Those that impacted the project in this PR are:

• Either all arguments fit on one line, or each argument is on its own line (see the changes in ILRepository for an example).
• Braces are always required on expressions if they don't fit on one line (see the changes in FakeAssetLoader for an example).

If you prefer to keep the previous behavior, let me know, and I'll adjust the rule accordingly.

Changes made

• Self-explanatory.
