This is a bit contrary to the original game, where each player would get
its own "Game over" event.

On real hardware I've noticed that individual bullets are barely
noticeable. Make them a bit thicker.

This is still missing the support for player 2, but I've left traces
about it.

For now this only applies to enemies, but it's general enough so it can
target any given coordinate, and hence any given object.

At first I thought that I could save up some space and then mirror the
sprite horizontally, but it actually makes things easier to have the UFO
enemy in its entirety as it makes initialization and moving the object
easier. This is indeed possible because we have plenty of room left on
the CHR bank.

This adds a first implementation of collision checks between the player
and the background.

This also corrects a pixel from one of the animations on the chr file.

This commit adds the skeleton for having a title and a main screen. For
now the title menu doesn't do much, as the selection is simply ignored,
but at least it already knows how to cycle between these two states.
