[Summit][v0.1.9] Big update that adds comment posting

Summit v0.1.9 is finally live on the play store after one of the longest reviews I've seen taking close to 5 hours.

This is a huge update and a lot of code has been changed.

This update adds the ability to post comments, edit comments and delete comments.

A detailed changelog is posted below.

• Added the ability to post, edit and delete comments
• Added a comment editor. Includes features such as text formatting, and comment previews. The ability to insert images in comments will be added in a future update.
• Added sort by subscribed
• Added support for heavily nested comments.
• Added support for spoilers.
• Fixed a bug where the upvote/downvote button would be unresponsive
• Fixed a bug where images in posts would have extra padding at the top/bottom
• Fixed a bug where the community posts will overlap if the user has no bookmarked communities, but has subscribed communities, the user left the app while on a subscribed community, came back to the app and tapped on the home community.
• Fixed a up where up/down votes would not update the UI
• Fixed the comment button on the community screen. The comment button will correctly jump into the comments of the post when tapped.
• Fixed a bug where the text of buttons was a weird shade of purple/blue. It is now just entirely black.
