VID-2050 Profile article comments with Bucky

Adds Bucky profiling calls to article comments code + Fixes lots of legacy js code issues, styling and whitespace.

Use the ?w=1 option for an easier diff read.
Let's just prefix with "ArticleComments". That would be more in line with what I've been doing and what I hoped to convey here https://one.wikia-inc.com/wiki/Engineering/Bucky#Prefixing_Bucky_Calls.
