Where filter does not handle truthy values correctly

[williamb1024]

When using the where filter with a single argument, the filter does not perform truthy comparisons. The equality comparison is performed with the property value controlling.

fluid/Fluid/Filters/ArrayFilters.cs

Line 156 in 74cb742

if (itemValue.Equals(targetValue))

Switching itemValue and targetValue, such that targetValue is controlling would result in truthy comparisons.
