Additional Content Sensitive Edit Links

This patch adds a few edit links into Content, Media, and Macro related editor to more easily navigate between related items.  For example if a editor is editing a document and notices a type in a property or needs to add a property; they have to navigate over to settings and find the appropriate content type to edit(witch could be many steps down a hierarchy tree).  This the minor change going to the Properties tab will reveal a Edit Content Type button that will go directly to the settings tab, locate the documents content type, and open it for editing.  Assuming you have access to it of course.

The following logical QuickLinks are added
Edit Content Type from Document
Edit Template from Document
Edit Media Type from Media
Edit Macro from Script File, Xslt File, or Partial Macro View.
Edit Script File, Xslt File, or Partial Macro View from Macro.

(I had original created this as a custom package but in reality this is such a minor change and is such a huge time saver, that it really should just be included in the UI by default.
