Improve event detail popup positionning (no above-positionning yet).

Browse source 
The popup is horizontally aligned with the click location, and 
vertically close to event (slightly on top of it, from below).

If the click occurs too much on the left or the right side of the 
screen, the horizontal position is shifted accordingly, so that it is 
never displayed outside of the screen. Note, however, that the small 
arrow supposed to point the related event is not shifted as well as of 
now (not as straightforward since it is a CSS pseudo-element).

This commit also removes the ability to display the popup _above_ the 
event in case the click occurs too close to the bottom of the screen. 
This feature should be reintroduced by a later commit once it will have 
been fixed :).
