Use PNG icons instead of BMP and XPM ones in the toolbar sample

Update the sample for the 21st century (with just a bit of delay) and
use PNGs under all platforms instead of using BMPs under MSW and XPMs
elsewhere.

Copy PNG icons from Tango, even if we already have almost of them in
art/tango because we plan to also use "2x" versions of them in this
sample soon.
