Add the ability to regenerate cultures (#495)

* Add the ability to regenerate cultures

- Added a button to the tools menu for regeneration.
- Regeneration button will handle initial generation of cultures and expansion afterwards.
- Pressing regenerate will warn the user.
- Small cleanup of trailing whitespace.

* Refreshing cultures editor updates culture centers

* Regenerating cultures refreshes the culture editor

* Added a function to refresh all open editors

* Reset burg and state cultures after regeneration

* Address the problem of potential data loss

Any errors while iterating the states or burgs could potentially lose the index 0 metadata stored in the arrays. This will instead track the index and ignore the 0th result.

* Religions update cultures on culture regeneration

Updated function names to be more similar and more descriptive
