Tooltips and small improvements

CSS:
-Pointer cursor in table cells
-better JS friendly formatting of event circles and tooltips
HTML:
-deleted "onload" and "onclick" events, now everything in JS
(performance improved)
JS:
-changed behavior of search button and input field (need to be
improved!!!)
-click at every table cell scrolls down to quickinfo
- improved a bit the responsiveness functions
-event circles getting smaller the moment they would wrap, but wrap
finally on the smallest resolutions (looking good though)
-TOOLTIPS!!!
load data from json
design is in early phase, needs improvements
