* introduce SystemConfig to avoid DI circle (used by database connection which is itself needed by AllConfig that itself contains the methods to access the config.php which then would need the database connection - did you get it? ;))
* use DI container and use that method in legacy code paths (for easier refactoring later)
* create and use getSystemConfig instead of query() in DI container

First step of a somewhat testable user management. - I know, the JSON returns are in an ugly format but the JS expects it that way. So let's keep it that way until we have time to fix the JS in the future.

Improve FileActions JS to allow for custom rendering

Partially fixes https://github.com/owncloud/core/issues/12690 - remark to myself: improve grep skills.

Check for working .htaccess via AJAX

This is a first draft. It has only been tested with the ownlcloud logger.
Some internal fields are JSON encoded several times which makes it harder to read.

Create config if it does not exists

Keep spaces out of the string

Otherwise translators cannot notice them on Transifex.

Fixes https://github.com/owncloud/core/issues/12650

The codepath that is executed when executing ownCloud via CLI is different than via browser. Specifically, the config is created by the user session already in `OC_Util::getInstanceId()` by a call to `setValue`. That said, this seems to be quite a bad side-effect, but for the sake of "not breaking whatever might break if we touch this" let's keep it that way for now.

When executing the autoconfig via `php -f index.php` the said session was not setup and thus no `config/config.php` file was created resulting in an installation error.

To reproduce this try to setup ownCloud via `php -f index.php` with and without that patch. (ensure to delete all existing configs before and don't access ownCloud with a browser in the meantime)

Fixes itself.
