Breaking changes

This is an important release towards stabilizing conan and moving out of beta. Some breaking changes have been done, but mostly to command line arguments, so they should be easy to fix. Package recipes or existing packages shouldn't break.
Please update, it is very important to ease the transition of future stable releases. Do not hesitate to ask questions, or for help, if you need it. This is a possibly not complete list of things to take into account:

• The command conan install doesn't accept cwd anymore, to change the directory where the generator
  files are written, use the --install-folder parameter.
• The command conan build now requires the path to the conanfile.py (optional before)
• The command conan package not longer re-package a package in the local cache, now it only operates in a user local folder. The recommended way to re-package a package is using conan build and then conan export-pkg.
• Removed conan package_files in favor of a new command conan export-pkg. It requires a local recipe with a package() method.
• The command conan source no longer operates in the local cache. now it only operates in a user local folder. If you used conan source with a reference to workaround the concurrency, now it natively supported, you can remove the command call and trust concurrent install processes.
• The command conan imports doesn't accept -d, --dest anymore, use --imports-folder parameter instead.
• If you specify a profile in a conan command, like conan create or conan install the base profile ~/.conan/profiles/default won’t be applied.
  Use explicit include to keep the old behavior.
