Don't load svg-painter.js on every admin screen

[johnbillion]

svg-painter.js gets loaded on every admin screen, but only user-profile.js uses it (on the user profile editing screen).

Isn't user-profile.js just re-initializing the painter on color scheme changes?

Otherwise the script is always initializing itself if the current browser doesn't support SVG:

	$(document).ready( function() {
		// detection for browser SVG capability
		if ( document.implementation.hasFeature( 'http://www.w3.org/TR/SVG11/feature#Image', '1.1' ) ) {
			$( document.body ).removeClass( 'no-svg' ).addClass( 'svg' );
			wp.svgPainter.init();
		}
	});

I think it is needed also for plugins that use SVG icons, to change the icon color on :hover (as far as I know it never worked on :focus). An example is an admin menu item with a SVG icon.
