Added the annual report page.

Used the collapsible feature of bootstrap
Removed the html, head and body tags in the mailing list file
Added the report tab in the menubar. Removed the newletter tabs and sub tabs.

Added a hr after the noticeboard.

But when the image is up, it won't be shown on medium viewports (as on stacking, it won't look good.)
