Allow volatile history

[f1reflyyyylmao]

In the settings storage section, I can set the maximum chat history of a server to a maximum to 1Mb. Would it be possible to make this value nullable so the history is deleted on app close when messages go out of memory? I'd like my irc history to not be permanently stored on my android phone, and 1Mb is still a humongous amount when considering it's olny plaintext.

I'm not sure how this is done in the app, if the messages are automatically written to the database when they're received so the maximum size mustn't be zero, the solution could be to add a "delete server logs on app close" option.

Any opinion on this?

Could use an in-memory store, althrough the server would be excluded from auto-reconnect in that case.
