Title: add propper bootstrap styles to flash messages

Just a little fix for displaying flash messages(including messages generated by devise) with proper twitter_bootstrap styling.
Version of Twitter Bootstrap which we're using now doesn't apply any styling to elements when we add a simple base class 'alert' to them (unlike previous version!), so we need to specify additional contextual classes like 'alert-info' or 'alert-warning' in order to get proper highlighting .
