Added an option to enable navigation menu on the left side of the scorm panel.
Navigation menu is built using the title tags of the items in the imsmanifest.xml file.
Leaf item tags are also clickable in the navigation menu which change the current page to the clicked page.
Added an option to specify width of navigation menu. Default size is 30% of scorm panel width, 70% is assigned to the course iframe.
Added a navigationClick check on GetValue scorm API call as Chromium blocked synchronous calls on page unload and we didn't want to make an API call when changing pages using the navigation menu.
Fixes #53.
