v1.9.23

-- Finally got rid of all use of and references to the unnecessary, confusing and hard to use tables CondName2Group, CondName2Run and CondName2Subj which mapped conditions local to runs and subjects to global group conditions and vice versa. Made it so that stims and condition are copied to proc stream as mutable acquisition properties edited manually through GUIs and consumed by proc stream processing. Furthermore the same set of conditions are used for all TreeNodeClass nodes. This set of changes makes the code for finding, displaying and processing stim conditions, trivially simple and clear.
