This was reported to me, that it makes no sense that csr, crt and so on
are written as 0700. And even in the case of private keys, why do they
need the executable bit set?
This commit is a complete rebuild of pkictl. Before everything was all
over the place and adding new commands was kind of a hassle.
Now each command has its own file and can be adjusted on a command
basis. Options are still used by the same name, but can now use
different descriptions.
