A fallback to preserve the 1.0 - 1.3 behavior of children in
templates having their startup called before the parent widget
fires postCreate. Defaults to 'false', causing child widgets to
have their .startup() called immediately before a parent widget
.startup(), but always after the parent .postCreate(). Set to
'true' to re-enable to previous, arguably broken, behavior.
A string that represents the widget template. Pre-empts the
templatePath. In builds that have their strings "interned", the
templatePath is converted to an inline templateString, thereby
preventing a synchronous network call.
Use in conjunction with dojo.cache() to load from a file.
