Item viewer changes & introduction of Utlities sub-namespace in resource object

Changes to Item_HtmlSubwriter
     Changed to be HTML5 compliant
     Stepped through and cleaned up all HTML
     Changed the name of all ids and classes to determine what is still in use
Doing the same for all the item viewers, but only part way through
Created a Utilities sub-namespace under SobekCM_Resource_Object and moved some existing classes there
Update to the Related_Images_ItemViewer to clean HTML and provide nicer overall look/feel
Merge branch 'master' of github.com:MarkVSullivan/SobekCM-Web-Application
