Add a custom value to set default flyspell correct direction.

[smcallis]

Hi I tweaked the script so that I can set the default correction direction. I usually ctrl-arrow up to get my cursor somewhere north of things and then run stuff so being able to correct forwards is a biggie for me. Thought you might like to have the change.

Hey @smcallis

Thanks for your PR. It's nice to have an ability for users to change default direction of correction. I remember there was a conversation about this some time ago in this thread. But I never found time to implement it.

Since a lot of time passed since then, maybe it worth just merging your PR and call it a day 😸 But if you wish to implement the proposed solution, I would be glad 😸

WDYT?

Happy to bang out a quick change however you like, could you summarize the final thinking in that thread on how people would like this to work?
