B9PartSwitch v1.6.0 for KSP 1.2.2

Changes

• Allow tanks to be partially filled - percentFilled can be defined on the subtype, resource, or tank type (in decreasing order of priority), defaulting to completely full
• Allow toggling resource tweakability in the editor - resourcesTweakable can be defined on the subtype or tank type (subtype takes priority), default is whatever the standard is for that resource
• Allow RESOURCE nodes directly on the subtype
  • If the resource already exists on the tank, values defined here will override what is already on the tank (won't affect other subtypes using the same tank)
  • If it isn't already on the tank, it will be added (won't affect other subtypes using the same tank)
• Add ModuleB9DisableTransform to remove unused transforms on models
• Major internal changes
