Update process from v1.x to v1.3

First of all, this is not an emergency update or anything.  If you are currently mid-game using v1.2.1 and do not want to lose the basements you've built, you can wait to upgrade until later, when you're ready to start a new game.

v1.3 does require a clean save if you are updating mid-game, which means the basements will completely revert!

Due to some scripting changes, this was unavoidable.  Again, DO NOT UPDATE if you don't want to have to do a clean save procedure and lose your basements.

If you DO want to update mid-game, here's what you need to do.

• BACK UP YOUR SAVE!  This is always a good idea in case you need to downgrade.
  
• Before upgrading, go into your basement and remove any items you wish to keep 'cos the cells are going to revert.
  
• Go aboveground to your settlement (leave the Basement)
  
• Save your game.  If you can use the console, use the savegame command and name it something descriptive like savegame "Updating Basement Living to v1-3"
  
• Quit and uninstall Basement Living v1.2.X
  
• Load the game you just saved, and click "Yes/OK" on the warnings about missing plugins
  
• Save your game one more time.  It's now "clean" of prior versions.
  
• Quit and install Basement Living v1.3
  
• Load up that most recent 'clean' save you made in the previous step and start making basements! Again, they will be reverted to their original form.
