//function: getFullPath
//description: converts relative paths into full paths that start with
//file:///
//Why this is important: A user is prompted for a location to save
//a file. Dreamweaver generates a path that is relative to the currently
//opened document. If a developer tries to use this URL in DWfile, it will
//not work because dreamweaver assumes the path to be relative to the 
//extension file. However, full paths will work
//Note that this function sometimes returns a full path that is indirect:
//For instance: file:///C|/MyWebSite/Hobbies/Cooking/.../Hobbies/Images/cake.gif
//However, the user never sees this file path.
//
//Arguments:
//filePathURL - doc-relative,site-relative, or absolute file path
