add some reference files for easier debugging/checking
add a specific check for invalid emote name
add check for single rotation-wrapper of right height for -brody-spin

- same issue crops up for -brody-brody-brody, or -spin-spin-brody, etc
add test case for supporting first/second line text and alt text css
add sample data for adviceajlie to use in new test case
rotation-wrapper logic to keep max height of wrapper
change regex to allow for alt text part in []
impl support for first/second line text and alt text
move the module exporting to a separate source file

- this keeps the individual classes from having to include
  any references to node, global, or exports
rename EmoteHtml.spec.js to EmoteExpander.spec.js

- since the class being tested is EmoteExpander, this makes more sense
new class and tests for creating emote string from EmoteInfo object
