'cached' parameter is boolean, not string

Currently checking if pkgng >= 1.1.4, as specified in
https://wiki.freebsd.org/pkgng . I guess that's when using PKGSITE was
deprecated.

Also solves the particular problem of installing packages that have multiple versions in the repo, but specifying the exact version would be troublesome:

$ pkg install -n dovecot
The following 2 packages will be installed:

	Installing dovecot: 1.2.17
	Reinstalling dovecot-2.2.6 (options changed)

$ pkg install -n dovecot-2.2.6
The following 1 packages will be installed:

	Reinstalling dovecot-2.2.6 (options changed)

$ pkg install -n -g dovecot-2*
The following 1 packages will be installed:

	Reinstalling dovecot-2.2.6 (options changed)

Could it be that easy or do I have missed something?

This reverts commit 4942a06b.

This also fixes an issue where some console output for packages I was
installing was creating invalid JSON because it contained single-quotes.

pkgin always returns 0 so can't be used to tell if the install or remove
worked.  Instead this just queries the installed packages after
performing an operation.
