FEATURE: allow for custom excerpt BBCODE

FEATURE: allow for custom excerpt BBCODE

This allows fidelity in controlling excerpt (text that shows up when you pin a topic or link to it externally):

I am some text

This is some **custom** markdown that should be the excerpt

More text

Previous solution relied on DIVs, unfortunately DIVs do not play well,
by design with mixing markdown unless you have a preceding newline eg:

<div class='hello'>

this will be treated properly as markdown


This extra newline is not desirable.

I am also considering adding

[div class=excerpt]

This would offer lots of flexibility to themes and plugins that do not want the extra annoying newline.
