Add Travis-CI integration.

Browse Source 
The only way to test travis is to deploy to master with a `.travis.yml` file and wait for travis-ci to pick up the change.  To do some pre-testing here, the `Vagrantfile` has been split into two distinct machines:

 * `default` is, as before, the full reddit build (we have an opportunity to rename this)
 * `travis` is a minimal install with only the packages and services required to run `nosetests` against the codebase.  It tries to mimic what will happen when we try to build this on travis-ci's workers.

As part of this addition, I've moved `install-reddit.sh` to `install/reddit.sh` and populated that `install` folder with common scripts used for both `default` and `travis` builds.

# This script installs a reddit stack suitable for development. DO NOT run this
# on a system that you use for other purposes as it might delete important
# files, truncate your databases, and otherwise do mean things to you.
#
# By default, this script will install the reddit code in the current user's
# home directory and all of its dependencies (including libraries and database
# servers) at the system level. The installed reddit will expect to be visited
# on the domain "reddit.local" unless specified otherwise. Configuring name
# resolution for the domain is expected to be done outside the installed
# environment (e.g. in your host machine's /etc/hosts file) and is not
# something this script handles.
#
# Several configuration options (listed in the "Configuration" section below)
# are overridable with environment variables. e.g.
#
# sudo REDDIT_DOMAIN=example.com ./install-reddit.sh

Congratulations! reddit is now installed.
The reddit application code is managed with upstart, to see what's currently
running, run
sudo initctl list | grep reddit
Cron jobs start with "reddit-job-" and queue processors start with
"reddit-consumer-". The crons are managed by /etc/cron.d/reddit. You can
initiate a restart of all the consumers by running:
sudo reddit-restart
or target specific ones:
sudo reddit-restart scraper_q
See the GitHub wiki for more information on these jobs:
* https://github.com/reddit/reddit/wiki/Cron-jobs
* https://github.com/reddit/reddit/wiki/Services
The reddit code can be shut down or started up with
sudo reddit-stop
sudo reddit-start
And if you think caching might be hurting you, you can flush memcache with
reddit-flush
Now that the core of reddit is installed, you may want to do some additional
steps:
* Ensure that $REDDIT_DOMAIN resolves to this machine.
* To populate the database with test data, run:
cd $REDDIT_HOME/src/reddit
reddit-run scripts/inject_test_data.py -c 'inject_test_data()'
* Manually run reddit-job-update_reddits immediately after populating the db
or adding your own subreddits.

# reddit dev environment installer
# --------------------------------
# This script installs a reddit stack suitable for development. DO NOT run this
# on a system that you use for other purposes as it might delete important
# files, truncate your databases, and otherwise do mean things to you.
#
# By default, this script will install the reddit code in the current user's
# home directory and all of its dependencies (including libraries and database
# servers) at the system level. The installed reddit will expect to be visited
# on the domain "reddit.local" unless specified otherwise. Configuring name
# resolution for the domain is expected to be done outside the installed
# environment (e.g. in your host machine's /etc/hosts file) and is not
# something this script handles.
#
# Several configuration options (listed in the "Configuration" section below)
# are overridable with environment variables. e.g.
#
# sudo REDDIT_DOMAIN=example.com ./install/reddit.sh
