Fix display of bookmarks on Android browsers.

Currently, bookmarks are hidden when viewed on Android and thus unusable.  There's also an issue for iOS, and I suspect they're related.  I haven't tested iOS, though.

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 form Ubuntu chrome @1080p.
