Professional Services for Piwik - neutral branding within Piwik app

When Piwik config file becomes un-readable, make it clear that the file still exists but is not readable (#10331)

* * In messages, make it more clear whether config file exists and/or is (not) readable
* When the config file exists but is not readable, provide users the choice between making the file readable, or starting a fresh install
* As long as Piwik is not installed, piwik.php should not return 500 when config file is not readable
* Fixes #10283
* UI tests: updated message when config file is not found

* Enforce the Minimum PHP version in composer.json using "platform" feature
Added in https://github.com/composer/composer/commit/a57c51e8d78156612e49dec1c54d3184f260f144

It was found that this flag is very important to use to make sure the package we build and release will be compatible with this PHP version.
Otherwise, the minimum PHP version enforced would be the version where our build script runs, which could be PHP 5.5 or PHP 7 which would have caused serious issues.

* Update doctrine/cache, monolog,piwik/network, piwik/cache, piwik/php-tracker  etc.
