wp_tag_cloud() not returning values

[ryanhellyer]

wp_tag_cloud() is not returning values when echo=false argument is used.

Allows wp_tag_cloud() to return value as intended.

true||false is only usable when you use array notation for calling template tags.

When using the string form within template tags, you need to use a 0 for a false value. This is consistent with all other template tags. In your case, you're passing the string "false" which PHP reads as a true value.
