Fix a couple of issues with closing channels.

Closes #782

Allow specifying a window for DisplayableEvents in format.yml (Issue #459)

Apply display properties to a value before running functions on it.

Make saveconfig save more than just identities. Issue #15

This allows "unstyled" to actually work.

Closes #755

I'm sure this will be changed/redone, but this is at least a start by allowing
certain events to go to all windows (eg ServerNotices)

Ideally it would be possible for some events to only be displayed in the window
that generated them (eg if I do /notice foo bar the ">-{{target}}-> {{message}}"
message only appears in the window I ran the command in, not either just the
server window or all the windows, but this would need changes to a bunch of
events to make them include a source window.

Fix errors from previous commits.

Add /reloadformat command.

Fix some unused imports/fields/etc.

Move config provider tests to the right place.

Remove legacy default colour behaviour.

We now specify the default colour using display properties, not
by ascribing special value to the first colour code in a message.

Closes #741

First pass at a style guide.
