BREAKING_CHANGE : $config['content_config']['escape'] and

A few days ago Parsedown released new ("stable") versions of Parsedown and Parsedown Extra: Parsedown 1.7.4 and Parsedown Extra 0.8.1. Parsedown 1.7.4 backports some features of Parsedown 1.8.0-beta-7 and is compatible with Parsedown Extra 0.8.1. However, due to these changes Parsedown Extra 0.8.1 now breaks compatibility with Parsedown 1.8.0-beta-7. Parsedown's release process is messed up beyond repair... Not sure what we're going to do now, this needs some research whether we can downgrade to Parsedown 1.7.4 without breaking things (what would require us to release a new major release, i.e. Pico 3.0). For now we're pinning Parsedown 1.8.0-beta-7 and Parsedown Extra 0.8.0-beta-1 as of Pico 2.1.0.
Pico doesn't require 'ext-dom' itself, Parsedown Extra does; Parsedown Extra didn't declare this dependency before, but Parsedown Extra 0.8 finally does.
In the future we'll use picocms/pico-composer to create Pico's release packages (and picocms/pico-composer depends on picocms/pico-deprecated and picocms/pico-theme by default). Installing picocms/pico-deprecated and picocms/pico-theme is no longer required, but rather suggested. You simply don't need them in any case. You need picocms/pico-deprecated only if you're using old plugins, and picocms/pico-theme is obsolete when using a 3rd-party theme.
Pico doesn't require the PHP extensions itself, but erusev/parsedown-extra does. The explicit composer.json requirements are necessary until erusev/parsedown-extra#85 gets merged. Both extensions aren't part of Ubuntu's default LAMP setup anymore.
Symfony YAML >= 3.0 requires PHP >= 5.5.9 and we're currently not planning to raise Pico's PHP requirement.
This reverts commit f251bc83ec995d05e0e33140df22a451c0cfe4af.
