Test for cross-platform SVG icon scaling

- Several PNG icons are switch out with SVG counterparts to test Qt scaling on different platforms
- Default theme has added SVG icons that are comprised of the regular PNG embedded within
- GIS theme has added mostly SVG 24x24 icons and one at 48x48 (also for touch interfaces)
- This commit's changes will probably be reverted after testing
