Remove monolithic compiled bootstrap javascript library

[zipymonkey]

Ideally, we'd include only javascript that is actively being used on every page. Javascript that is not needed globally should be included a specific library that is then included only when needed. An example of this is are the carousel library.

Task

• Update mix command to copy individual javascript files from node_modules/bootstrap
• Add individual js files to targeted libraries (accordion, carousel, etc).
• Add remaining javascript to global_styles library
