My editor also caught some extraneous whitespace at the ends of lines.

Back out Custom Post type changes to fix whitespace issues.
Complete merge for Custom Post Types filter.

Includes whitespace fixes and new filter type for custom post types.

This version of the code doesn't make a big deal about the fact that
they are custom post types. It simply lists the post types (including
the built-in 'Blog Post' and any custom post types that have been
defined).
