/*
Written by Chris Jean for iThemes.com
Version 1.7.0

Version History
	1.3.0 - 2012-10-09 - Chris Jean
		Added the builder_get_pixel_widths and builder_get_percent_widths functions.
	1.4.0 - 2012-10-12 - Chris Jean
		Improved the builder_get_percent_widths function.
	1.5.0 - 2013-07-01 - Chris Jean
		Updated the storage of the default Layouts and Views to use a three format system: JSON, serialize+base64, and serialize. This is to avoid issues with servers that have problems properly reading the data.
	1.6.0 - 2013-08-09 - Chris Jean
		Added builder_import_theme_default_layouts_and_views().
		Use value from builder_import_theme_default_layouts_and_views() when setting up default Layouts if the function returns a non-empty result.
	1.7.0 - 2013-08-15 - Chris Jean
		Updated the theme importer to properly use the built-in importer system.
