  Fix Dynamic Hints Variable Substition - Underscore Problem

  When adding a dynamic hint, if an extension contains an underscore no variable
  subsitution is being performed.

  This patch changes from checking if the extension contains an underscore to
  checking if the extension begins with an underscore.
