• Make sure that the flash events are invoked after a handler had a chance to bind [#10]
• Changed default alerts to never autohide [#6]
• Bootstrap handler: All conventional Rails notices are correctly styled by @conzett [#12]
• Turbolinks are supported thanks to @yoyos [#13]
• Fixes to cookie nuking by @asaletnik [#7]
