Changeset 3153 for trunk/GSASIIplot.py

Message:

Add choice of setero projection & equal area inv. pole figures in Phase/Data? window
make inv. pole fig plotting/tool tip & cursor position all agree. Use proper coordinate system for cursor position.
NB: k-axis horizontal; h-axis up, so one is looking down l-axis for inv. pole figs.
