Remove some unused methods.

Add display property to suppress timestamps.

Formats defined in YAML can specify 'timestamps: false' to hide
the default timestamp for lines associated with that event.

Closes #633

Fix some build warnings.

Use the right annotation to subscribe.

Make LogUtils more robust.

Also make event bus errors have a better message.

Closes #627

Allow plugins to specify event formats.

Closes #622

Use snapshot version of raven, send relase.

This enables release tracking in sentry.

Propagate exceptions sanely.

Use the new MutliEventFormatProvider.

Issue #622

Add format provider that handles multiple sources.

This will allow plugins to supply their own format providers
while still allowing the user to override them using the
main format.yml file.

Issue #622

Update to MBassador 1.2.4.

This release contains some performance improvements compared
to the version we were using.

Error handlers are now passed in at construction time, so
there was a small bit of refactoring required.

Add info about how to display text...

Disable numeric formatting, remove dead code.

With numeric formatting gone, all output is either added direct
to a window (which will be changed soon) or done through
displayable events. Message sinks are now completely unused,
as they don't affect displayable events.

Issue #426

Improve formatting of whois events.

Add ugly event-based whois output.

This allows events to iterate over a collection property, and
adds formatting for whois results. It needs a lot of tidying,
but it's a start...

Add formatter support for before/after templates.

This allows formats that may be multi-line (whois results,
probably MOTD results at some point, etc...) to show a header
and footer around the actual content.

Couple more deprecation fixes.

Remove most deprecated methods in commands

Deprecate things that should be replaced by events

Move some more formats over to events.

This allows us to remove a fair chunk of the notification
handling functionality in FrameContainer.

Issue 426

Make topics have proper dates.

Tidy up some unused/uncommonly used methods.

I think these will eventually go away entirely, once everything
is event-bus'd, but I'm not entirely sure how that works any
more :(

Minor tidying around displayable events.
