 */

/*  UPDATES
	
	1.4.0 - * replaced some path code in place of the plugins_url function
			* added the "webphysiology_portfolio_use_full_path" option to allow for the ability to have images, and some
			  css/js files, specify full pathnames. there seem to be instances where some hosts don't like HTTP:// within
			  the image pathnames and some cases where they require it.  go figure
			* added code to handle image paths needing adjustment in a multisite install
			* updated inclusion of ShrinkTheWeb script to utilize wp_enqueue_script and specifically un-register any
			  instances that were registered as "stw-pagepix", which is how WordPress Portfolio Plugin registers it.
			* added deregister of thickbox resources to try and avoid contention with other plugins, like Auto Thickbox Plus
			* added support for displaying a single portfolio screen
			* added back the ability to preview a single portfolio record
			* added function for gathering plugin options and returning them within an array
			* added PagePeeker service support for thumbnail generation
	1.3.2 - * added support for Options page WEBphysiology social buttons
			* better isolated navigation controls by adding "webphysport_nav_top" and "webphysport_nav_bottom" classes.
			  top and bottom classes will be deprecated in a later release.
			* added embedded portfolio CSS for new webphysport_odd_stripe and webphysport_even_stripe classes.
			  odd and even classes will be deprecated in a later release.
			* enhanced the "has_shortcode" function to utilize a different method to obtain the current page's content as
			  using "the_content()" was causing issues with some theme's page titling
			* added declaration for inclusion of a new IE7 and below stylesheet
