Fix broken JS in xhtml

Add height: auto to video element css

This allows plugins to easily render a <tfoot> element in a table, even
though it's not used in standard table syntax it makes sense to have it
available.

using icons from https://materialdesignicons.com/

more complex material design icons can be somewhat larger than 1kb

This introduces a new dokuwiki\Ui namespace and refactors the Admin
screen into a Ui class. The ultimate goal is to split up the big,
complex functions in inc\html.php in better maintainable classes in the
Ui namespace. This is the first go at it. Others function->class
conversions should follow.

This also switches the icons for our base admin plugins to inline SVG.
(files and styling not included, yet).

This introduces an embedSVG() function that can be used at other places.

http://stackoverflow.com/a/33005329/172068 tells us that we never need
to send it when it's zero. Which it always is for GET. That means we can
always send it for non-zero values.

Allow form dropdown options as arrays with numeric keys

This should ensure it has the same lastmod timestamp as the revision it
stores.

This updates the SimplePie RSS parser to the recent 1.4.3 release,
fixing an PHP 7 bug (and probably others). We now use a composer based
install.

Fix problems in authpdo

Without the change in issue #1801, or commit
1b26d16d respectively, this adjusted
test would throw an error since it would attempt to use another array as
an array-key.

The fact that the test passes without error means that the bug is fixed.

The problem this is solving is that PHP does not allow for array-keys to
be strings of ints. It always converts them to actual ints. This caused
a problem when trying to use complex array-options with integers as
keys.
