Big mess of updates, breaking our rules on "commit little and often" because the code was so ugly. This revision will be broken for the WinForms UI, but as MonoDevelop/eSVN don't have a way of committing multiple projects in one go it can't be helped (Eclipse's Team Sync view could handle it) Fixes #122: Make usage of percentage or ratio common * All usage of ratio amounts for equipment items should now assume percentage * Properly calculate number taken for ratio selection (divide by 0 now we're using percentages) Fixes #118: Allow equipment amounts of "ratio" equipment to be define as absolute or ratio amounts * Added extra commands that differentiate between ratio and absolute amounts Fixes #120: Numeric limit equipment items show large percentages * Now made formatting treat ratios as percentages (don't multiply by 100) * Move string formatting to UnitEquipmentItem...Selection classes * Add method to Unit to say whether an equipment item is a numeric or ratio amount
