This description-string-only commit changes the remaining references to
"configuration parameters," opting instead for the less ambiguous
"configuration settings" (or just "settings").

The classes key of an ENC's output can contain a hash instead of an array, as
of Puppet 2.6.5. This commit updates the description of the external_nodes
setting accordingly.

…rator instead of ':'

We were interpolating the File::PATH_SEPARATOR character in the desc string to
display the actual character being used on the platform on which it is
printed. This is marginally useful when running with --genconfig, but since
the config reference properly lives online, it should be platform-agnostic for
the benefit of Windows users.

The default values of several configuration settings (diff, color, daemonize)
are different on Windows, but these differences did not appear in the online
configuration reference, as it is generated on a POSIX system. This commit
adds notes on these differing defaults to the description strings of the
affected settings, to ensure that the configuration reference remains
accurate.

This commit replaces some unclear text about "recursive symlinks" that dated
from 2006.

This commit tightens up the huge description of the source attribute, by:

* Explaining the recommended puppet URI format instead of the complete format
* Fixing a misleading example to use puppet URIs instead of local files
* Calling out the source/content/target trichotomy
* Inserting an example of how module layout maps to puppet URIs

This commit clarifies several descriptions.

This commit documents symbolic modes (added to the file type in issue #2927).

* Mention that the magic search bit behavior only applies to numeric modes
* Add brief syntax for symbolic modes
* Add brief syntax for numeric modes
* Explicitly call out that we translate Unix permissions as a metaphor on other
  platforms

This commit adds the following Win-specific information to the file type's documentation:

* No symlinks
* Puppet doesn't translate line-endings (that is, content is managed in binary mode)
* Paths need drive letters
* Use / in paths, not \
* Users can be groups and vice-versa
* Other maps to Everyone
* r/w/x map to FILE_GENERIC_READ, FILE_GENERIC_WRITE, and FILE_GENERIC_EXECUTE
* User permissions should be superset of group which should be superset of other
* Mapped drives are OK for file sources

This commit adds mention of the following to the user type's doc strings:

* The windows_adsi provider manages local users, not all kinds of users.
* Windows users don't have a gid or shell attribute.
* Windows passwords are cleartext-only.
* Most platforms use sha1 for passwords, OS X Lion uses sha512.
* Puppet treats user names case-sensitively, regardless of the platform's rules.

As of commit 9b8829d, allowdupe works on
FreeBSD, tested (per commit message) on versions 7, 8, and 9. The
compatibility warning was never removed. This commit brings that doc string
back in line with reality.

This commit mentions that:

* Nested groups aren't supported.
* Puppet treats names case-sensitively.
* The GID property is read-only on Windows.
* We only do local groups.

This commit makes minor changes to the wording of the Windows service
provider's documentation, and mentions that one should use the short system
name for a service rather than the display name.

This commit documents the following:

* install_options are package-specific; there is no master list of these, so
  users must check the vendor's documentation.
* MSI provider needs a source.
* MSI provider can't uninstall arbitrary packages, just the ones Puppet installed.

This commit mentions the following in the Windows exec provider docs:

* You can use the old 2.6 pre-shell-provider workaround to use shell built-ins.
* PowerShell scripts won't work unless you change the default execution policy.

This commit:

* Makes the documentation of the trigger attribute more legible
* Adds details on accepted input formats to the trigger attribute docs
* Does minor wordsmithing and reformatting
* Calls out issues with versions < 0.2.1 of the win32-taskscheduler gem
