v5.2.0

More plausible usernames. A middle name gives john.m.smith, jmsmith, johnmsmith; a double surname gives either name (maria.santos or maria.silva); particles between the parts (da, von, bin, ...) are left out, but kept at either end of a name (Anh Do, Van Helsing). The ten name shapes are weighted (john.smith 22%, johnsmith 17%, jsmith 14%, ...). Digits are most often a year, then a small or lucky number or a pattern; the new nickname_request.birth_year makes the real year, in two or four digits, the likeliest ending. About one in thirteen gets a prefix (the, real, its, iam) or a suffix (official, hq, irl). The gaming style is unchanged; username output differs from 5.1.0.
