Consolidate most module code into spack.modules and spack.cmd.module

Browse Source 
- One file with all the module classes (spack/modules.py)
  - Has an EnvModule superclass that does most of the work and consolidates common code
  - Subclasses have specializations for different module systems (TclModule, Dotkit)

- One command (spack module) for all the types of modules to use
  - the one command is used by the scripts, only need to maintain in one place
  - has some subcommands for different module types, but they're handled mostly generically.

- Consolidate zsh support into a single setup-env.sh script.

"""This module contains code for creating environment modules, which
can include dotkits, tcl modules, lmod, and others.
The various types of modules are installed by post-install hooks and
removed after an uninstall by post-uninstall hooks. This class
consolidates the logic for creating an abstract description of the
information that module systems need. Currently that includes a
number directories to be appended to paths in the user's environment:
* /bin directories to be appended to PATH
* /lib* directories for LD_LIBRARY_PATH
* /man* and /share/man* directories for LD_LIBRARY_PATH
* the package prefix for CMAKE_PREFIX_PATH
This module also includes logic for coming up with unique names for
the module files so that they can be found by the various
shell-support files in $SPACK/share/spack/setup-env.*.
Each hook in hooks/ implements the logic for writing its specific type
of module file.

#
# This file is part of Spack and sets up the spack environment for zsh shells.
# This includes dotkit and module support as well as putting spack
# in your path. Source it like this:
#
# source /path/to/spack/share/spack/setup-env.zsh
#
#
########################################################################
# This is a wrapper around the spack command that forwards calls to
# 'spack use' and 'spack unuse' to shell functions. This in turn
# allows them to be used to invoke dotkit functions.
#
# 'spack use' is smarter than just 'use' because it converts its
# arguments into a unique spack spec that is then passed to dotkit
# commands. This allows the user to use packages without knowing all
# their installation details.
#
# e.g., rather than requring a full spec for libelf, the user can type:
#
# spack use libelf
#
# This will first find the available libelf dotkits and use a
# matching one. If there are two versions of libelf, the user would
# need to be more specific, e.g.:
#
# spack use libelf@0.8.13
#
# This is very similar to how regular spack commands work and it
# avoids the need to come up with a user-friendly naming scheme for
# spack dotfiles.
