Add color the shell name.

The bug in #166 is actually that the second shell is red instead
of green as required in the XML. This will be resolved later,
hopefully.
Make the second shell now the green one. Fixes #166.

Grant the player a tiny second of invincibility when hitting big pip, and offset him slightly. Fixes #216.

This ensures that a) the player does not immediately get hit by one of
the two little pips that are created (which is very hard to avoid
without this invincibility period), and b) that the player does not
get stuck on one of the pips, which previously happened easily when
you jumped onto pip at the left edge.
