If the $_SCROTT['AUTO_MODAL'] global is defined, it will refer to a
modal's DOM ID to be shown once the page loads.  Currently, an error
state will supersede this and display the notice modal instead.

Since there is little text labeling things in the navbar, I have added
popup tooltips to each button (link) and dropdown menu.

When viewing a pad, offer the 'New Issue' option under the additions
menu in the navbar.  Will will display the just-added new issue modal,
for the user to open a new issue on the first stage of the pad being
viewed.

Updated the javascript to wire-up the issue list items shown on pad
views.  When these are clicked the associated issue modal is displayed
in the foreground.

Removed placholder text and now displaying the logged-in user's display
name.  This is accopanied by the user icon and (conditionally) the
'cool' sunglasses icon for admins.  This is similar, but not identical,
to the markup of my old archived code I'm clearing out.

This additional spacing is added to the navbar text to improve its
appearance in the browser.

Updated old settings modal design, to incorporate added Scrott features.
Reimplemented this modal in Scrott from archived code and have included
it in the navbar.
