* Support for ::slot() overflow hidden/visible added
* Proper support far ::slot() background properties
* Support for template background in combination with slot backgrounds
V1.1.1
* Added support for comma-seperated selectors
* Fixed background positioning for body templates.
* Added support for setting template display/position properties using jQuery().css()
V1.1.2
* Added/fixed support for width/height set in CSS for elements in a slot
* Allow fallback class to be set, to hide fallback CSS rules
* Improved display property parsing, corrected handling of incorrect width values
* Added support for spaces between minmax() values
* Added $.templateLayoutShowOnReady to hide the non-template rendering.
* Added support for sub-templates with same letters
V1.1.3
* Fixed IE bugs
V1.1.4

V1.1.5

V1.1.6-bb
* Now using grid/flow properties instead of display/position
