This addresses issue #6427: it adds the ability to have polynomials for parameterized families of fields on Galois group pages. There is currently data for degrees through 10, some in degree 11, and a few scattered groups after that. To see an example,

http://127.0.0.1:37777/GaloisGroup/5T4

which is one of the few cases where it gives more than one family, and shows that individual polynomials can be marked as generic.

http://127.0.0.1:37777/GaloisGroup/4T3

shows that it can display that a family is generic for fields except in certain characteristics.

For a particularly complicated polynomial, view M24

http://127.0.0.1:37777/GaloisGroup/24T24680

In all cases, the user can use the raw/typeset feature to copy polynomial for a computer algebra system.

Looks great to me! I made a few code tweaks that won't affect how anything is displayed. I'm happy to merge once tests pass, though perhaps it's worth giving other people a chance to take a look and make comments.

FYI, I just copied gps_regular_polynomials to prod.
