This goes through and fixes up the remaining complaints from ESLint.

Most fit into the following categories:

Missing or unused variable declarations.
Missing blank lines around blocks, before return/break, or before

expect() for Jasmine.
Spacing/indentation/alignment issues.
Missing semicolons.
Complex one-liners.
switch formatting and now-required fall-through comments.

Verified ESLint was happy with the final results.
