Sidenotes instead of alerts

replace alerts (not the .alert examples) by sidenotes.
* Remove alert-heading class, which no longer exists in CSS.
more specific comment, better placement of code
Merge branch '3.0.0-docs1' of https://github.com/juthilo/bootstrap-wip into juthilo-3.0.0-docs1
swap all bold p tags in sidenotes for h4s
fixes #7191 and cleans up indenting some
more indenting
IE8 doesn't need help with responsive images, they work just dandy apparently (see http://jsbin.com/idesit/1)
Restore  on links in dropdowns as they are randomly breaking onto new lines
