Remove closing slash as per Joomla Coding Guidelines

[PhilETaylor]

Just removing a closing slash from an img tag to make @C-Lodder a happier little boy

Ensure user provided data is correctly encoded.

Dedent lines 34 and 35.

I understand that this was not in the original code. In \plugins\fields\imagelist\tmpl\imagelist.php, directory is accounted for. Does it apply here? If yes, probably should be in a separate PR.

	if (!$path || $path == '-1')
	{
		continue;
	}

	if ($fieldParams->get('directory', '/') !== '/')
	{
		$buffer .= sprintf('<img src="images/%s/%s"%s>',
			$fieldParams->get('directory'),
			htmlentities($path, ENT_COMPAT, 'UTF-8', true),
			$class
		);
	}
	else
	{
		$buffer .= sprintf('<img src="images/%s"%s>',
			htmlentities($path, ENT_COMPAT, 'UTF-8', true),
			$class
		);
	}

There is a lot more than just removing the slash in this PR

[N6REJ]

I don't see where the / is added back

[N6REJ]

@PhilETaylor ok, then I'm really confuzzled because then we're breaking html?

[brianteeman]

@N6REJ no we are not. html5 does not require the /

[N6REJ]

@PhilETaylor I think I'll go back to contemplating why the hamster spins the wheel ... thanks

@franz-wohlkoenig
This works for a media custom field (same now as imagelist).
I get here OK

dl class="fields-container">
			<dd class="field-entry ">
			<span class="field-label">imagelist: </span>
<span class="field-value"><img src="/testnew/trunkgitnew/images/joomla_black.png" class="imgclass"></span>
	</dd>
</dl>

and for media

<dd class="field-entry ">
			<span class="field-label">media: </span>
<span class="field-value"><img src="/testnew/trunkgitnew/images/powered_by.png" class="mediaclass"></span>
	</dd>
