Added Reset Button

[theshubhagrwl]

I have added a Rest Button to reset all the styles but I need some help.

Currently the reset button is resetting back to the original styles visually. Visually in the sense that we can see the styles change on the frontend but the data which is sent to the backend is not changing, So for that I need some help.

I have made all the changes in here : https://github.com/theshubhagrwl/cssify/tree/reset-button
