Add additional functionality for `parseMeta`

* Some adherance to STYLEGUIDE.md
* Some routine optimization
* Additional parameter for `parseMeta` to not clobber a parsed metadata block e.g. not normalized
* Default to normalized meta with existing stored Object on S3
* Add normalized flag to all existing `parseMeta` calls

Applies to #232 and eventually #243 and #53
Add other upmixes for keys that have way too many synonyms

* Alphabetize final target
* Alphabetize uniques
* Add `@icon` to uniques... this should prevent multiple icon values from being downloaded to save user bandwidth

Applies to #232
Fix undeclared variable in strict mode
