REL: Pre-Alpha release 0.0.1

This pull request includes updates that were necessary to make qiita usable
when installed via pip, this is a summary of the changes:

- Classifiers and documentation strings in `setup.py` have been updated.
- `setup.py` now imports and installs the resources that are needed for the website to work properly (templates, static resources, etc).
- The webserver is no longer started by running the nefarious `python qiita_pet/webserver.py`; to start the webserver simply do: `qiita webserver start`.
- The inclusion of the `webserver` subcommand into the `qiita` needed the import of the application to be done as part of the subcommand itself, therefore you will see that `from qiita_pet.webserver import Application` is not at the top of the file.
- `qiita webserver start` includes an argument to specify the port `--port`.
- The installation documentation has been updated to reflect the current status of the project.

:warning: Note :warning: that I won't upload to pypi until:

1.- this PR is merged.

2.- We can get rid of this package https://pypi.python.org/pypi/qiita/0.1.1 @wasade, I think you created that, can you remove it? If that wasn't you @wasade, does anyone know about who created that?
the demo user is also included in the test environment by default, so this command may or may not fail if they specify TEST_ENVIRONMENT=TRUE in their config.  Also, why not load ontologies?  The ontologies will be useful to everyone who is installing qiita.
