Changes (by kosmikus):

  * milestone:  cabal-install-0.14 => cabal-install-0.16


 The following works now:

    * Constraints and preferences can be added to the global config file.
    * Each `constraint:` or `preference:` line can specify only a single
 constraint, but several such lines can occur.
    * Config file constraints will be handled like command-line constraints
 by the solver.

 This can be used to specify a personal blacklist.

 However, the following remains to be done:

    * Make it easier to work with several config files. Currently, we can
 reset the config file, but not use a stack of config files. `cabal-dev`
 allows the latter.
    * Distinguish config file constraints from command-line constraints in
 error messages.
    * Allow a single config file line to contain a list of constraints.
