[WIP] Improve profile : add to bottom of map 

Here is a WIP version of the new profile (see enhancement #1729). 

[Test link](http://mf-geoadmin3.dev.bgdi.ch/ltkan/src/?X=196144.36&Y=599921.89&zoom=8&lang=fr&topic=ech&bgLayer=ch.swisstopo.pixelkarte-farbe&layers_opacity=0.75)

It doesn't meet the 'scope statement' yet, but we already have : 

- the box and the d3-profile as well are responsive with the window browser (even on language change events)
- the box is no longer dragabble and to the bottom
- control buttons are on the rigth side for a better user experience ;)
- stats are summarized on the left side with a refined design
- show/hide button still switches between standard measure tool and profile tool
- there is still space for new stats on the left side and new buttons on the right side (e.g altitude change, highest/lowest point, zoom to transect button, normalize profile...)
- compatible ie9

Still to do : 

-  the profile box width should be reduced when the main geoadmin panel is extended and going over the profile.
- adapt print
- cross-browser compatibility
- hide svg-profile if window size is lower than a value
- css bugs to fix
- add smooth transition to the switch measure tool / profile tool
- center transect to the middle of the map

And optionally :   
- replace the reduce button

- show the surface type based on geocover
@oterral the problem is that when I use document.getElementByClassName fpr the offsetWidth, it returns me a NaN value, and not with Id.
