Avoid the use of deprecated MariaDB "zero dates" globally. If they're present
as attribute defaults somewhere, they will be replaced with NULL implicitly.
The existing "zero dates" in MariaDB storage will be left intact and this
should not present any issues.
The "timestamp" type in table definitions now corresponds to DATETIME in
MariaDB with "DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP", which
should be close enough to the original behaviour for compatibility purposes.
It is now the recommended type for "modified" attributes, because of the
update trigger on MariaDB. But there is no such trigger implemented on
PostgreSQL as of this moment.
The code used to operate under the assumption that MariaDB doesn't support
quoting identifiers. Not only is that not exactly true, but MariaDB has
reserved keywords that cannot be used as table or column names unquoted.

Default supported files need to use consistent names. Bumped version to 1.20.0
ImageFile has been changed to extend MediaFile and rely on it to partially
validate files. This validation has been extended to not rely solely on
Fileinfo, as it is disabled on some places. Now it'll try to use the shell
command `file`, if Fileinfo isn't available.
ImageFile now converts every new upload to PNG, except JPEG and GIF, which
are kept, but still resized (to the same size), to remove possible scripts
embedded therein.
MediaFile::fromUpload will return an ImageFile if the uploaded file is an image
or a MediaFile otherwise.
MediaFile can be constructed with an id with value -1 to denote a temporary
object, which is not added to the DB. This is useful to create a temporary
object for representing images, so it can be used to rescale them.
The supported attachment array needs to be populated with the result of calling
`image_type_to_extension` for the appropriate image type, in the case of images.
This is important so all parts of the code see the same extension for each image
type (jpg vs jpeg).
Added documentation to classes/File.php and to lib/MediaFile and lib/ImageFile
