fix typo in sql query
Shorten the GBM covtype perf test
hack to deal with non-enum col having nan in vec.min() or vec.max()..algo needs min 2 deep histogram (max_qbins+1) ..code was creating a 1 deep for the special case of nans in vec.min(). kind of ugly (exec was creating an empty key and causing the issue) ..but it seems to work

fix up the CSS on these pages
Don't call toUpperCase() on column names in Inspect1 (leave them be)
Don't have hover-over effect on ToFactor/ToInt custom css
boolean ops on enum cols are odd

For == and !=, result is a boolean col.
For all other ops, result is a col of NAs
put unifiles2 back to pointing to covtype etc

we kind of have hacky handling of all ilegal cases. like enums or empty keys where the vec.min/max is bad. for enums, we currently reject and don't build the qbins object. So then when the QuantilesPage looked to get the requested param stuff back, it got an NPE...for now, just know not to look for stuff if qbins wasn't built..maybe should build it with minimal return info
some perf/accuracy tests
Minor API polishment.

The min, max, mean fields in Vec should be private
to avoid accidental accessing of fields without calling rollupstats
(since the fields are initialized lazily)
