Hides conversations in the messages dialog with specific users, and stops those users from appearing as suggested recipients of posts when you click share.

A work in progress. Currently, you'll have to manually create a key "hidethese" in the values tab with an array of usernames as the value.
I wrote this userscript because being constantly reminded of a friend who died suddenly whenever I opened the messaging panel or clicked "share" on Tumblr makes me really sad, and I didn't want to block my deceased friend or delete their messages. I just wanted to hide them in a way that was fully reversible.
This doesn't hide reblogs, replies or askbox messages. Only conversations in the messaging area, and the suggestion to share a post with the specified users.
