Added bounce and rotate enter/exit modules.

TO DO:
 - wrap modules in boolean check
 - Add mixin to class
 - Replace hardcoded values with Sass variables from settings file
Added missing semicolon - fixed compilation error
Added remaining modules to main stylesheet
Removed compiled css file from repo
(this should be generated when working on a project by using the sass --watch command)
Added compiled stylesheet to ignore list as we no longer want to track it's changes while working on the repo
