Styled Venue List page- changes to markup are inline on venue*.html page. TODO: cleanup periscope.css to free it of repeat entries and check it with other .HTML documents to make sure it's compliant.
Combined all CSS styles into periscope.css (contained in venue list dir) and sidebar.css (contained in dashboard page dir). TODO: localize sub2.png asset for login page. TODO: balance min-height for mini-tron-panel.
