Put cartoony bomb texture back, again.

Texture does not pay attention to the on screen size or UV mapping
and ignores the stylistic decissions behind STK's look.

As explained in r10873 ("svn log data/models/tnt-bomb.png"):
New one is not cartoony, has pixelated zones itself (stick and clock
"circles"), tiny details that are invisible most of time that create more
pixelation (arrow edge appears only over red), shading does not match and
seams do not match (stick and clock, cylinder to "lids").
