included info-icon in mobile view back again (due to request from Frank
(see comment in JIRA ticket #875))
adapted size and layout of info-box (when user hovers over info-icon)
for mobile view (up to 480px)
changed max-width in media-query for responsiveness from 480px to 479px,
since there is another media-query with min-width 480px... so that the
range of both queries don't overlap for the case of 480px.
reverted change of max-width (since I found that this is not necessary
in css)...
changed media queries in such a way that now in mobile view the content
and title inside the info-box (if user hovers over info-icon) are
displayed side-by-side instead of in 2 different lines.
removed mediaquery for 670px. put its content to mediaquery for 767px
for reasons of consistency.
