SIC - missing n1 ADL status

Updated Table 1's so now ADL status change is set to the stable category from
the n0 interview if the n0 interview has the ADL status
Also added a table to show the number of observations this change affects
for each of the criteria
Spouse data - minor

updated comments, added sql count when ran through generating new
6-12m chronic condition variables
Spouse factors - exclude nursing home residents

added two new sections to run univariate and then logit models when
the group that reports n1 nursing home residence, didn't change results though
