Get rid of backup copy that keeps getting searched.
Issue #51 Upright orientation of manipulandum.

Changed wording to mention holding the manipulandum upright. Pictures
were also changes (see DexPictures).
Issue #54 Show tapping deployed.

Changed the picture and text so that the instructions to move to the
blinking target are compatible with the tapping surfaces being deployed.
Issue #50 Look at targets in targeted preview.

Changed the message to prompt the subject to look at the actual
targets. Also changed the picture so that there is no ambiguity. This
addresses a comment by a crew member that said it is best if the
pictures always change from one step to the next.
Issue #56 Show were VISIBLE indicator is.

Added a new picture that shows where the VISIBLE status indicator is on
the touchscreen. It is used during the Configuration tasks.
