Abstracting AMP validators and sanitizers into AMP Library

[marcelovani]

On this pull request I did the following:

• Removed the submodule https://github.com/xwp/wp-dev-lib.git and requested it as composer package, which will be checked out inside the vendor folder
• Added a require for autoloader.php in the vendor folder
• Moved the bash script and python script to re-generate the validator classes into the AMP-Library, see this pull request https://github.com/dennisinteractive/amp-library/pull/6/files
• Fixed the bash script that installs WP to delete the table before creating it
• Removed the generated class-amp-allowed-tags-generated.php, this will now live in the AMP-Library
• I have done a quick hack to replace the AMP_Content class with \Lullabot\AMP\AMP(). This needs to be done properly buy my WordPress skills are limited.

private function build_post_content() {
    $amp = new \Lullabot\AMP\AMP();
     $content = apply_filters('the_content', $this->post->post_content);
     $options = array(
      'scope' => 'body',
      'add_stats_html_comment' => false
    );
    $amp->loadHtml($content, $options);
    $this->add_data_by_key('post_amp_content', $amp->convertToAmpHtml());
    $this->merge_data_for_key('amp_component_scripts', $amp->getComponentJs());
    $this->add_data_by_key('post_amp_debug', $amp->warningsHumanHtml());
    return;
