MultiCriterion.to_q (used by SessionFilter for game/device) unconditionally added
field__in=value even when value was empty, and __in=[] matches no rows — so a
filter with only excludes (e.g. device excludes 11, no game/device includes)
returned zero results. Guard the empty value like ChoiceCriterion already does,
so an exclude-only criterion means 'all rows except the excluded ids'.

FilterSelect fully replaces it: delete SelectableFilter and its _selectable_*
helpers, the now-unused _get_filter_options, selectable_filter.js, and the .sf-*
rules in input.css (rebuilt base.css). The three list views load search_select.js
instead of selectable_filter.js. Drop the SelectableFilter export and refresh
docs/comments that referenced it.
