Enable chat history (#180)

* Temp chat lifecycle rule only applies to tmp/ now

For safety's sake, we applied the rule to *all* files initially;
but now we're going to enable chat history, so we only want the
temp file logic to apply to the temporary file directory.

* Disable temporary chats

This is a minimal way to re-enable chat history for all. There's
other code still left that is geared towards a temp-chat-only
solution that I've left in the codebase (such as showing temp chats
in the sidebar history), in case we change our mind again.

If we eventually let users choose chat history vs. temp chats, we
should take care to remove that special logic later. For now, I'm
assuming that we either want all chats to have history, or none of
them.

* Removed temporary chat notice from sidebar

Now that all conversations are saved, this is no longer relevant.

* Remove references to temporary chat from FAQ

Now that we're retaining all conversations, that part needs updating.

* Update language in FAQ for chat history

* Update comments after removing temp chat

* Fixed typo
