Foreign keys delete and update actions

[Soleyu]

Added logic to create table so that it can parse on delete and on update clauses. Now you can just add on_delete and on_cascade directly as arguments instead of making a query to enable for example on delete cascade.

I added this mainly because I was annoyed to having to do a query and it seemed like a small change to do.

Also, I seem to have polluted it with a commit I did to change something, Im sorry about that Im a bit new with this, on that note, if I did this whole pull request wrong and should have done soemthing else in order to submit stuff then I apologize.

Hello @Soleyu
Thank you for working on this 😃

I would like to request some small changes to the if-statements 😄

Also, the formatting check job (Static Checks / Format (clang-format)) fails atm so that it something you'll need to fix.

[Soleyu]

The last commit should resolve any issues I think. Also thanks for having patiencve with me!

Hello @Soleyu,

Everything seems to be good with the code now 😄
Would it be possible to squash your commits into one?
