Avoid failure on PHP 5.3.3  by manually encoding the single quotes

Created unified system for running tests in travis for Piwik Core and any Piwik plugin. System includes a console command (generate:travis-yml) that generates a .travis.yml file for a plugin or core. The travis file will check in travis if it needs to be updated, and if so it will fail the build and tell the user. If a specific command line option is specified supplying a github user token, the .travis.yml file will be updated within travis automatically.

Notes:

  - comments and non-travis sections will be preserved
  - includes logic for plugins to test themselves against latest stable version instead of just on master
  - the system is primarily controlled by environment variables. developers can change/add variables in .travis.yml and the auto-updating will preserve the changes.
Maybe fixing tests
.travis.yml file is out of date, auto-updating .travis.yml file.
Skip a test for 5.3.3 and do not allow failures of Integration tests
