Title: Reset slug input text box after invalid input.

No Issue
* When an invalid, all whitespace slug is entered into the
slug input in the post settings menu, it's rejected but
the input's value still remains the same. This resets the
input back to its original value.
* Convert whitespace from tabs to spaces in post-settings-menu.hbs
