New Profile: 2160p Balanced (#20)

tweak(regex): Better descriptions

tweak(profile): Modified Blu-ray behavior for Quality profiles
- Score set to 10, so that non reputable encodes are not ranked above web-dls
- Quality tier scores increased to make up for this

create(profile): Initialise Profile: 2160p Balanced
- New CF: 2160p Encode - used to negate any encodes at 4k
- New CF: Lossless Audio (1080p) - used to negate non-reputable encodes w/ lossless audio from overtaking wanted WEB-DLs
- New Profile: 2160p Balanced - grab 2160p WEB-DLs with fallback to 1080p Quality
