Merge branch 'release/4.2.4' into develop
Added noConflict() so multiple versions can be included in the same context safely.
Added files and directories Bower should ignore.
Renamed 'context' => 'exports' and '_EventEmitter' => 'originalGlobalValue' based on feedback from @Wolfy87.
Merge branch 'bower' of https://github.com/MonkDev/EventEmitter into MonkDev-bower
Merge branch 'no-conflict' of https://github.com/MonkDev/EventEmitter into MonkDev-no-conflict
Pedantic tweaks to jstayton's improvements.

Just spacing and a change to the JSDoc. The EventEmitter class is
actually of type function, not EventEmitter. I just want to make sure
the typing is accurate to the JavaScript, even if it looks a bit off.
Bumped version numbers to v4.2.5.
Added a test for sub-strings. Confirming #63 close.
Built v4.2.5.
Updated the documentation.
