Inline Text Replies

[mattyg]

As a user, I can reply to some specific text within a Mew. Similar to how you can comment on selected text within an article on Medium.

overview

• modify the Reply mew type to specify the starting character index and length of text I am replying to
• modify the UI for displaying a Mew such that reply mews also show the snippet of text they are replying to as a quote
