Abstract animations to be its own modular component

[sebnitu]

Ultimately, I want to remove animations from being applied to any one specific block component. Instead, I want animations to be abstracted in it's own module where it can be applied as needed to specific cases of blocks and components.

Animation styles could be used similar to this project by Daniel Eden: https://daneden.github.io/animate.css/

Block components that would use animations include dropdowns, modals, tabs, tooltips, notices, flash messages, etc. Applying a global animations module to these would reduce repetition and create a simple way to plug and play css animations.
