Fixes #260

Description

• Updated browser-sync
• Updated gulp-autoprefixer
• Updated gulp-clean-css
• Updated gulp-jshint
• Updated gulp-rename
• Updated gulp-replace
• Updated gulp-sass
• Updated gulp-zip
• Added sass dependency because gulp-sass removed the compiler. It is now just a gulp wrapper for sass.
• Updated gulpfile to correctly use the new compiler
• In an attempt to fully update gulp-notify, removed the 'sound: false' options. It didn't fix the errors from gulp-notify version 4, so it is still at version 3. I left the changes because they weren't necessary regardless.

How Has This Been Tested?

Updated all dependencies and ran gulp package. Output successful.
