Initial release.
Provides two Views sort handlers that fix string fields containing numbers sorting alphabetically instead of numerically.
Cast sort wraps the field in a CAST(field AS type) expression before sorting. Supports integer (unsigned and signed), decimal, date, datetime, and text cast types, all configurable in the Views UI. Works on all Drupal-supported databases. Best for fields that store purely numeric values as strings: SKUs, reference numbers, serial numbers, rankings.
