Login page: new design

[sergiocontrino]

we should start moving the look of the login page to something similar to the one proposed by sarah.

some of the needed icons should already be in the repo.

please comment here if something missing/unclear

thank you @Swarnalathaa : here my suggestions. it is possible that we need some iconic help form sarah.

• [x] - i would use bold for writing inside the buttons
• [x] - footer: i think that eufunding banner, [about, mdr, user guide] and the 3 icons should be bigger
• [x] - footer: the 3 icons should be links to the projects page
• [x] - the 3 lines menu should be bigger
• [x] - ecrin and oslo should be links
