[Release][v0.1.13] Cache improvements, Post actions & More

Pretty standard release with the usual stuff. The next thing on the roadmap is "settings" which was named super vague on purpose. This will be fun.

If anyone has something they'd like to configure, drop it in the comments. I can't implement everything but I'll try my best.

Changelog:

• Cache user subscriptions. User subscriptions will continue to refresh on app load, however a cache will always be shown.
• Fix a bug where “set as home” will not work if the user is already on the home “tab”. (Fun fact, the app treats each community on the left pane as a “tab”. Each tab actually has it’s own history).
• Change the behavior of the home button. If the home button is tapped when you are at the top of page 1 of a community page and you are not on your home page then you will be taken to your home page.
• Added the ability to create, edit or delete posts.
