[WIP][v1.23.0] WIP

Just going to implement as many of the user requests as I can until I have a good amount done and go for a release.

Changes so far:

• Added "reason" to mod logs.
• Changed the following admin/mod actions to open a dialog which allows you to provide a reason: remove post, undo remove post, remove comment, undo remove comment, purge comment, purge community, purge post, purge user, ban user from community, ban user from site, remove community, hide community.
• Added two new admin actions: remove community and hide community.
• Fixed a bug where changing accounts while browsing a community will not load the correct community.
• Fixed a bug where mods/admins listed on the community/instance information screen do not have instance information.
• Added indicators on the community info screen for the hidden & removed state.
