* Remove unnecessary reference assigment
Proposed code is PHP5 and PHP7 compatible. PHP5 interpreted `$e->$type[$attr]` as `$e->{$type[$attr]}`, but the expected behavior based on workaround is consistent with PHP7 interpretation: `($e->$type)[$attr]`. By using curly braces `{$e->$type}[$attr]` there is a forced interpretation order working for both versions.
Details can be found on https://www.php.net/manual/en/migration70.incompatible.php (section "Changes to the handling of indirect variables, properties, and methods")
* Fix syntax
Use correct syntax for indirect variable evaluation order change.
The %HTML.Forms directive enables Forms module regardless of the %HTML.Trusted
value. This adds support for form elements without enabling other unsafe
modules, such as Scripts, Iframe or Object.
To achieve the same effect without this directive one has to explicitly list
all enabled modules in %HTML.AllowedModules, and any not listed will be
removed. This however is not very convenient, as the allowed modules may vary
between doctypes.
Resolves#213.
The purpose of this addition is twofold. In trusted mode, iframes are
now unconditionally allowed.
However, many online video providers (YouTube, Vimeo) and other web
applications (Google Maps, Google Calendar, etc) provide embed code in
iframe format, which is useful functionality in untrusted mode.
You can specify iframes as trusted elements with %HTML.SafeIframe;
however, you need to additionally specify a whitelist mechanism such as
%URI.SafeIframeRegexp to say what iframe embeds are OK (by default
everything is rejected).
Note: As iframes are invalid in strict doctypes, you will not be able to
use them there.
We also added an always_load parameter to URIFilters in order to support
the strange nature of the SafeIframe URIFilter (it always needs to be
loaded, due to the inability of accessing the %HTML.SafeIframe directive
to see if it's needed!) We expect this URIFilter can expand in the future
to offer more complex validation mechanisms.

When specifying source material for <object> tags, you must use
data inside the object tag as well as specify movie in a param.
If you specify a src (which is the appropriate markup for <embed>)
we now convert and fill in the other attributes appropriately.
Also, fix a PHP warning in Generator code.

This commit is a limited implementation of the "active formatting
elements" algorithm implemented in HTML5, which preserves certain
formatting elements such as <a> and <b> when exiting or entering nodes.

* Added Charsets and Character attribute types
* Fix a heavily recursive form of ContentSets, this allows a content-set
to include another content-set which includes another content-set, and
so forth.

Prior to this commit, the name attribute was unilaterally removed, except
for Strict doctypes or a heavy TidyLevel, when it was converted to an id
attribute. As name is actually permitted in both HTML 4.01 Strict and
XHTML 1.0 Strict, although deprecated, the more sensible default behavior
is to allow it unless TidyLevel is heavy.
Our implementation is slightly stricter than the specs, as name attributes are
treated as first class IDs, disallowing <a name="foo" id="foo"> or duplicate
names. The former should be treated as a special case, but that will be
a separate commit.
