Subject: [PATCH] installer: Add NTFS support.

This adds support for creating and editing NTFS partitions. It is however not
possible yet to create root NTFS partitions, as overlaying on top of a fuse
partition does not seem supported.

* gnu/installer.scm (installer-program): Add "ntfs-3g" to the inputs.
* gnu/installer/parted.scm (user-fs-type-name, user-fs-type->mount-type,
partition-filesystem-user-type, create-ntfs-file-system,
format-user-partitions): Add NTFS support.
* gnu/installer/newt/partition.scm (run-fs-type-page): Add NTFS support.
