Fix family in family selector

Dr. Zirbel has data for (c|t)HS not SH as I expected so I changed the family
names to reflect this.
Fix IDI cutoffs

I know use the correct IDI cutoffs from the base pair and isostericity paper.
Remove unused variable
Refactor heat maps of different summary properties

This cleans up the code for it some what. However, there are still problems with
it, for example we should never show the count or resolution as -1 in a tool
tip. That's never good. In addition, we seem to have some problems with keeping
the count the same between the table and the heatmap.
Use a patched version of tipsy
Better checking if combination exists and ranges

We now do a better job in checking if the sequence combination in the summary
table exists. If not we will now always display a grey square. In addition, the
range to use for count is dynamically generated, but topped off at 400 to make
the cWW family more understandable.
