StorePathCommands: Build installables 
So for instance "nix copy --to ... nixpkgs.hello" will build
nixpkgs.hello first. It's debatable whether this is a good idea. It
seems desirable for commands like "nix copy" but maybe not for
commands like "nix path-info".

Set default installable 
Thus

  $ nix build -f foo.nix

will build foo.nix.

And

  $ nix build

will build default.nix. However, this may not be a good idea because
it's kind of inconsistent, given that "nix build foo" will build the
"foo" attribute from the default installation source (i.e. the
synthesis of $NIX_PATH), rather than ./default.nix. So I may revert
this.

Interpret any installable containing a slash as a path 
So "nix path-info ./result" now works.

Make StorePathsCommand a subclass of InstallablesCommand 
This allows commands like 'nix path-info', 'nix copy', 'nix verify'
etc. to work on arbitrary installables. E.g. to copy geeqie to a
binary cache:

  $ nix copy -r --to file:///tmp/binary-cache nixpkgs.geeqie

Or to get the closure size of thunderbird:

  $ nix path-info -S nixpkgs.thunderbird

Add "nix eval" command 
This replaces "nix-instantiate --eval". The result is evaluated
strictly since this seems more useful.

getDerivations(): Filter out packages with bad derivation names 
In particular, this disallows attribute names containing dots or
starting with dots. Hydra already disallowed these. This affects the
following packages in Nixpkgs master:

  389-ds-base
  90secondportraits
  lispPackages.3bmd
  lispPackages.hu.dwim.asdf

Eelco Dolstra 2040240e23
Add a Config class to simplify adding configuration settings 
The typical use is to inherit Config and add Setting<T> members:

  class MyClass : private Config
  {
    Setting<int> foo{this, 123, "foo", "the number of foos to use"};
    Setting<std::string> bar{this, "blabla", "bar", "the name of the bar"};

    MyClass() : Config(readConfigFile("/etc/my-app.conf"))
    {
      std::cout << foo << "\n"; // will print 123 unless overriden
    }
  };

Currently, this is used by Store and its subclasses for store
parameters. You now get a warning if you specify a non-existant store
parameter in a store URI.

Move note about float support out of the wrong release notes 
Looks like this snuck into the 1.11 release notes post-release, but
float support isn't actually present until 1.12.
