Apply object display properties when formatting events.

If an object in a formatter tag ({{foo.bar.baz}}) is Displayable,
then we will modify the output based on its display properties.

Currently only supports user links and foreground colours.

This also changes the internal format of nickname links to be
`\u16<nick to link to>\u16<text to show>\u16`, allowing the
link and text to differ. This means if you formatted users
by showing their realname, you could still click them to
open a query.

Closes #424
Closes DMDirc/Plugins#507

Add a display property for linking to users.

Issue #424

Add base interface for objects with display properties.

This will allow the formatter to check if strings coming from
(for example) users in channels should be formatted specially,
such as by colouring or linking them.
