Make a features folder

[ghostdevv]

Now we are expanding beyond just commands/events to include buttons (#171) and soon things like modals (#182) it may make sense to not require a new directory per item.

Instead of

commands/
buttons/
modals/
...

features/

Name "features" is a work in progress, but seen it in other frameworks

Pros:

• One place for all items
• Less documentation needed

Cons:

Let me know any feedback/ideas

Possible suggestion for name: components

Suggestion: app
