feature/resourceRefactor

• Rename powers cost field to resources
• Implement a new syntax for the automatic manipulation of resources via powers:
  • For numeric resources (command points, ki, custom resources):
    • +N resourcename to increase the resource value
    • -N resourcename to decrease the resource value (asks confirmation if <=0)
    • N resourcename to override the resource value
  • For binary/flag resources (momentum, focus, custom resources):
    • +resourcename to set the resource value
    • -resourcename to unset the resource value (asks confirmation if already unset)
    • resourcename to test the resource value (asks confirmation if unset)
  • Note: Custom resources always display as numeric but can be treated as flags (0=false, 1=true, useful for math in inline rolls)
• Support handling multiple (comma-separated) resources in resources field
• Support resource name localization
• Support inline rolls in resources field
