Add additional haircuts for deductions and credits

[andersonfrailey]

This PR adds additional haircut options for a number of credits and deductions and fixes a minor error in the UBI function's docstring. There was nothing in the naming convention regarding what to name variables related to credits in this situation so I went with CR to start the haircut variables applied to credits. I'm happy to change that if there is consensus on a better option.

The point is to allow a user to repeal credits and all above the line deductions. Here are the new haricuts and what they are applied to:

Variable	Description	Type	functions	Hair Cut
e07240	Retirement Saving Credit	Credit	NonRefundable Credits	_CR_RetirementSavings_hc
e07300	Foreign Tax Credit	Credit	NonRefundable Credits	_CR_ForeignTax_hc

@andersonfrailey, Thanks for all the new policy parameters in pull request #1247.
I've looked this over and run it through my test suite and it all seems good.

Unless you have any other changes you want to make, I'll merge #1247 into master later this morning. Let me know if #1247 is finished or if you plan additional changes.

@martinholmer, nothing more to add in this PR. Thanks for looking it over!
