* Modules: Deduplicate suffixes but don't sort them.
The suffixes' order is defined by the order in which they appear in the configuration file.
* Modules: Modify tests to use spack_yaml.load_config.
spack_yaml.load_config ensures that the configuration is stored in an ordered manner. Without this change, the behavior of the tests did not match Spack's.
* Modules: Tweak the suffixes test to better catch ordering issues.
* new package: py-textblob
add variant to py-nltk to allow for data download/installation
add dependencies to py-nltk so that bin/nltk works
* add resources and resource generation script
* spack config: default modification scope can be an environment
The previous model was that environments are the highest priority config
scope for config reading operations, but were not considered for config
writing operations. Now, the active environment is the highest priority
config scope for both reading and writing operations.
Now spack config add, spack external find and spack compiler set environment
configuration in the environment by default if an environment is active. This is a
change in default behavior for these routines, but better matches the mental
model for an environment taking precedence over the user's default config file.
* add scope argument to 'spack external find' to choose non-default scope
* Increase testing for config modifications on environments

At some point in the build phase a script
spack-src/scripts/convert-template
has a shebang looking for python in the path.
Currently this picks up system python if in invoker's path, but should
be using python from spack, so add a build dependency on python.
Many system-installed binaries (at least in Debian) are built against a
libtinfo.so that has versioned symbols. If spack builds a version without this
functionality, and it winds up in the user's LD_LIBRARY_PATH via spack load,
system binaries will begin to complain.
```
$ less log.txt
less: /opt/spack/.../libtinfo.so.6: no version information available (required by less)

The 'external_modules' attribute on a Spec, when read from a YAML
configuration file, may contain extra formatting that is lost when
that Spec is written-to/read-from JSON format. This was resulting in
a hashing instability (when the Spec was read back, it would report a
different hash). This commit adds a function which removes the extra
formatting from 'external_modules' as it is passed to the Spec in
__init__ to ensure a consistent hash.
