Read page size from svg xml element #13

This MR addresses opening svg file with widths and heights expressed in mm instead of px.

Modifications:

function loadFile call readPageSize which is reponsible to update mediaSize with just loaded document
readPageSize open the file with QDomDocument and extracts fields width and height from svg tag
stringSizeToMm convert a size string to a mm float value testing if its unit is mm or pixel (in this case dividing by ppm)

Ah I think I actually already did this in develop. Sorry I really need to merge that into master but there's an issue that I haven't debugged yet where it leaves the cutter in some kind of broken state after one cut and you need to turn it off and on again. :-/
