Change normalization factor in popularity ranking calculation

Suggested by Hinoe, quoting his reasoning:
In popularity rankings, change the normalization from
"sqrt(LowerVoteCount)" == "LowerVoteCount^0.5" to something that grows
somewhat more slowly.
Details: Natural logarithm itself (ln(LowerVoteCount+1)) is too slow;
at the current VN count (15403), it returns 9.64; however, sqrt(15402)
is just above 124.1, which I feel is already too high. After
experimenting with the exponents a bit, I decided that the best point
likely lies between 0.3, which returns a bit above 18.0, and 0.4,
which returns a bit above 47.3. Thus, I suggest that the new function
be LowerVoteCount^0.36788; the exponent is a 5-digit approximation of
e^-1, just because it's a nice number in the specified area and works
well, returning circa 34.7.
