Add runPostActionsOnFailure to scheme

[FranzBusch]

Short description 📝

Schemes have an additional option to run post actions even on failure modes. This is particularly useful when you want to run a script to track something like the build time after any build concluded.

Solution 📦

I added a new attribute to the scheme runPostActionsOnFailure similar to the already existing buildImplicitDependencies attribute.

@pepibumur Would it be possible for you to take a look here?

This looks great @FranzBusch, thanks for adding it. Would you mind updating the changelog? After that we can merge and release a new version of XcodeProj
