Add The Ability for Users to Favorite Templates

Feature Details

Using localstorage to add the ability for users to favorite templates, as mentioned in #69

[MathPow]

If we are going to stick with the current card design, how will the user "star" a template? Do we add a icon? Where do we put it?

[ShaanCoding]

I will follow up later today with some refinements of requirements on this one. Thanks for wanting to pick this work up

Pending Review of #93

Closing due to scale and not really needed in scope, if interested @MathPow please reopen the ticket later after re-raising PR
