* PrivData converted to newtype (API change).
* Stopped stripping trailing newlines when setting PrivData;
this was previously done to avoid mistakes when pasting eg passwords
with an unwanted newline. Instead, PrivData consumers should use either
privDataLines or privDataVal, to extract respectively lines or a
value (without internal newlines) from PrivData.

the type UserName = String were changed to use them.
Note that UserName is kept and PrivData still uses it in its sum type.
This is to avoid breaking PrivData serialization.

My code with some improvements from weinzwang.

* Property has been converted to a GADT, and will be Property NoInfo
or Property HasInfo.
This was done to make sure that ensureProperty is only used on
properties that do not have Info.
Transition guide:
- Change all "Property" to "Property NoInfo" or "Property WithInfo"
(The compiler can tell you if you got it wrong!)
- To construct a RevertableProperty, it is useful to use the new
(<!>) operator
- Constructing a list of properties can be problimatic, since
Property NoInto and Property WithInfo are different types and cannot
appear in the same list. To deal with this, "props" has been added,
and can built up a list of properties of different types,
using the same (&) and (!) operators that are used to build
up a host's properties.

* Added CryptPassword to PrivDataField, for password hashes as produced
by crypt(3).
* User.hasPassword and User.hasSomePassword will now use either
a CryptPassword or a Password from privdata, depending on which is set.

This is not a complete fix for the problem that Info doen't propigate
from the called property when code does something like:
do
hostname <- asks hostName
ensureProperty $ foo hostname
Instead, I just eliminated the need to implement hasPassword that way,
by making the PrivData Info use a HostContext which automatically
gets the right hostname passed to it.
All other uses of withPrivData don't have the problem. It's still possible
for the user to run into the problem if they write something like the
above, where foo is a property that uses privdata. However, all properties
that take a Context now also accept a HostContext, so it's at least less
likely the user needs to write that.

the Context for the password. To specify a different context, use hasSomePassword' and hasPassword' (API change)

This is to work around OSX's brain-damange regarding filename case
insensitivity.
Avoided moving config.hs, because it's a config file. Put in a symlink to
make build work.
