Summary: Modify HTML component so you can style elements inside it.

Overview:
Details:
html.lzx:
- Added setStyle method to html.lzx. This sends the id/name/value of the
element to style to the iframemanager.
iframemanager.js:
- Added setStyle method to set the style of any element (by id). Any
errors generated are caught and discarded.
- Moved calling asyncCallback until the end of __gotload(). There was a
subtle race condition when you generate the onload event before setting
__loading to false. In my case, the onload event generates a number of
callJavascript() calls back into the iframemanager and expects an
immediate return of the data.
- Added check in setZ to ignore setting z to a null value. setZ is
called by code in html component using the z value from the sprite.
However, I found some cases where the sprite hasn't initialized the z
value.
Tests:
This test will style a div element in the html component when you click
the button.
test10.lzx:
<canvas height="600">
<simplelayout />
<button onclick="parent.myhtml.setStyle('mydiv', 'backgroundColor',
'yellow')">Change Color</button>
<html name="myhtml" width="400" height="100" src="test10.html"/>
</canvas>
test10.html:
<body>
<div id="mydiv">Div text to be styled.</div>
</body>
