Fix box shadow

[cbeauchesne]

Bulma was updated from 0.7.5 to 0.8.2

It comes with a modification of box shadows : jgthms/bulma@43b4b0b#diff-b5269e4512a3320cf8759fe9490361b1

Even if I personnaly like the new style, it's not coherent with other part of the UI (and touching the design should be discussed with community) :

From :

To:

Old style :

$box-shadow: rgba(10, 10, 10, 0.1) 0px 2px 3px 0px, rgba(10, 10, 10, 0.1) 0px 0px 0px 1px;

I did a check when upgrading the lib, I missed this point, sorry.

As for implicating the community, true, but for such a minor point I do think it is a bit useless. Well, if you have the will for this, I won't prevent you from it :)

Definitly not the will to start a discussion for this shadow, I'll only set it to the old value :)
