Fix display of bookmarks on Android browsers.

Currently, bookmarks are hidden when viewed on Android and thus unusable.  This also fixes the same display issue on iOS.

This branch has two commits: 
    Fix bookmark display on android browsers. -  Adds a width/height to #rightcontent.
    Allow for longer titles in bookmarks at the expense of overlapping the date and edit button. - Expands the max-width for bookmark titles from 24% to 66% as over half of my bookmark titles were cut-off when viewed from Ubuntu, Google Chrome @1080p.
