Round.java default is HALF_EVEN

[skfs]

Hi.
The "round" filter (Round.java) uses the default rounding in DecimalFormat.class which is HALF_EVEN.
I believe that HALF_UP may be the correct, but I have no data/reference to back this up.
HALF_UP rounds all numbers up when the decimal is higher or equal to .5, whereas HALF_EVEN rounds to the nearest neighbour (as do HALF_UP), but when equal distance to the neighbour, it rounds to the value that is even. So 10.5 becomes 10, and 11.5 becomes 12.
At least in Denmark the default rounding is always to round upwards when reached .5 in decimal.

Actually I just created a temporary Shopify shop and made a template that uses {{ 10.5 | round }} .
The final result is: 11, so Shopify rounds HALF_UP.

@skfs @bkiers I submitted a pull request (#108) that switches this to HALF_UP RoundingMode.

Thanks for raising the issue @skfs and @mbaumbach for the quick fix!
