Re #118: Allow equipment amounts of "ratio" equipment to be define as absolute or ratio amounts * Use new commands created in previous revision Re #122: Make usage of percentage or ratio common * Make sure all usage of percentages are correct Re #117: Add percentage and number boxes to equipment item dialogs * Fix some enable/disable inconsistencies for percentage amounts * Fix problems where fixed limits weren't honoured by widgets
