CCL: new feature s=spl (split-list) that splits terms in a search into
sub-phrases of all sizes (from 1 up to the number of terms) with order
preserved. For 3 terms the CCL search
a b c
is turned into PQF:
@or @or @or @and @and a b c @and "a b" c @and a "b c" "a b c"

Solr: don't set defType=lucene in URLs if extraArgs already defines it.
