KKS port and project code merge

[IDontHaveIdea]

Hi,

Just:

• added Stiletto.Core project
• moved code from Stiletto project to Stiletto.Core updated dependencies
• added configuration for conditional compilation
• added Stiletto.KKS updated dependencies
• added conditional compilation steps to compile the plug-in for KKS

Did not look in depth into Stiletto_KKS since the code is so different it was easier to work on the Stiletto code base.

I don't use Studio so no testing there. It seems to work fine in KKS.

For the method OnHeelInfoUpdate had to use try {} block. It gives and error the second time you invoke Maker in the same
game session. Don't have KK installed for testing this change in the code for KK. Though logic dictates that the problem should be present in KK also. The nullchecks fix if active will permit the plug-in to continue to run as is the case in KKS.

Thank you for the PR! The changes look good overall, just some minor issues to button up.

If you are going with the KK codebase, are you sure the KKS version didn't have anything worth keeping? e.g. fixes or UI changes.

[IDontHaveIdea]

Just a fast check the code for the Stiletto_KKS compiles as is for KK but I can't test if it works in KK.

[ManlyMarco]

Alright, let me know when it's ready for a review.

Nice work! I'm happy to give it a try on KK and see if anything is obviously broken.

[Splendide-Imaginarius]

No obvious breakage in about an hour of testing in both KK and KKS (mostly KK). I'll try to do some additional testing in the next few days, but so far LGTM.

[Splendide-Imaginarius]

Tested in KK for another couple hours, no issues connected to this PR. I did find a bug in the shoe warp feature, but I'm 90% sure that's a bug in master branch that I accidentally introduced while optimizing that feature at the last minute, not this PR's fault -- I'll send in a PR to fix that after this PR is merged, so that we don't have to deal with merge conflicts.

@IDontHaveIdea is there anything you still need to do before this gets merged?

[ManlyMarco]

@Splendide-Imaginarius I merged it since the issues appear to have been resolved. Feel free to send PRs now :)
