refactor: renamed validate-commit-msg to validateCommitMsg to keep consistency with other file names
fix: added changelog.js & validateCommitMsg.js to bower ignore list
test: added tests for changelog.js & validateCommitMsg.js. Run with `gulp jasmine`.

Since those two files are node modules, I had to use gulp-jasmine. I couldn't test it with karma since karma is for browser tests only.
