Title: added significant figure rounding to numeric_scale filter

Added an option for rounding to a specified number of significant figures in the `numeric_scale` filter.

This covers most cases, however, as we're using floating point numbers, there is the odd scenario where you'll still see lots of decimal places. This will probably have to be sorted by the spacenear.us uploader.

[With reference to issue #179]
