Amulet test fixes:

* Makefile: Only run precise-icehouse and trusty-icehouse tests by default
    and increase test timeout
  * t/00-setup: Simplify dependencies install
  * t/README: Mention charm-tools dependency
  * t/basic_deployment.py:
    - Specify unstable charm deployment
    - Use dicts in add_services
    - Rename restart test
    - Cleanup on test failure

 This directory provides Amulet tests that focus on verification of swift-proxy
 deployments.
 
+In order to run tests, you'll need charm-tools installed (in addition to
+juju, of course):
+    sudo add-apt-repository ppa:juju/stable
+    sudo apt-get update
+    sudo apt-get install charm-tools
+
 If you use a web proxy server to access the web, you'll need to set the
 AMULET_HTTP_PROXY environment variable to the http URL of the proxy server.
