Title: Add false option to eliminate separator all together.

Sometimes having a separator is not necessary and, as such, this new option will allow users to eliminate the separator.

I originally coded this using the [new WordPress standard for braces](http://make.wordpress.org/core/handbook/coding-standards/php/#brace-style), but other items of code in that section do not use braces for single line conditionals.
