Removed the remote partner and added a between-subjects reputation-salience condition.

The RCIT and the distance-ranking task are gone, too.
Removed matched trials.
Present all non-catch trials twice.
Updated instructions.
Clarified in-task instructions.
Improved random-assignment scheme.

My deployment script will fill "cas" with adjacent pairs of 0s and 1s, so we get random assignment with maximally equal group sizes.
