Apple cert management is PITA

[pavjacko]

Describe the solution you'd like

@sanderlooijenga feature suggestion decoupled from #398:

I also have a suggestion regarding the decrypt command. When trying it for the first time, I ran into the following issues;

After decrypt

We had to manually install the certificate
We had to manually install the provisioning profile
Maybe RNV can do something about that or have better error handling.

Thanks in advance :D
