Replace global see_cell by observe_cell and disambiguate old uses.

Calls to plain see_cell(pos) were replaced with either observe_cell(pos)
or you.see_cell(pos). observe_cell where related to drawing the
interface and messaging, you.see_cell for game mechanics, and
one or the other in less clear cases (targetting, say).
