Global : disable user select text

[scco]

by apply to html/body/app whatever

html { -webkit-user-select: none; /* Safari */ -ms-user-select: none; /* IE 10 and IE 11 */ user-select: none; /* Standard syntax */ }

so the app feels less like a website , more like a real application.
for parts that people should be able to copy for what ever reason, you can explicit enable that feature of select text.
