UncheckedProperty for cmdProperty et al
* Properties that run an arbitrary command, such as cmdProperty and scriptProperty are converted to use UncheckedProperty, since they cannot tell on their own if the command truely made a change or not. (API Change) Transition guide: - When GHC complains about an UncheckedProperty, add: `assume` MadeChange - Since these properties used to always return MadeChange, that change is always safe to make. - Or, if you know that the command should modifiy a file, use: `changesFile` filename * A few properties have had their Result improved, for example Apt.buldDep and Apt.autoRemove now check if a change was made or not.
