Configuration fixes for stock and KIS parts

[Technologicat]

• Fixed config for KIS parts: the large containers with crew tubes (ILC-18k Container, ISC-6K Container) are now passable.
• Added config for new stock parts in KSP 1.0.5: MK1CrewCabin, mk3CargoRamp.
• The stock shielded docking port is now passable also when surface-attached, to match the behavior of the regular docking port.
• The stock lander cans now have their bottom nodes always impassable; this was already enforced by 'freedom' but not by 'default'.
• Reorganization to improve maintainability: removed 'CLSStock Alternative Configs.zip'; now there is only one copy of the default config, CLSStock.cfg, and the 'freedom' config has been converted to an add-on containing configs only for the additional optionally passable parts. This fixes an issue where the mk3 parts had no CLS configs for users with the 'freedom' config, or with the version of the default config from the zipfile (which had drifted out of sync with the main copy).
• Minor cleanup: whitespace, one filename, ordering of some parts in CLSStock.cfg, use consistent format for all configuration entries (filter by HAS, add module if it does not exist). See commit log for details.
