43272: added support for ui:repeat to all gMap* subcomponents.

Testing notes: This will require regression testing as well as creating a new test for each gMap* subcomponent, where a bunch of subcomponents are added to the page using ui:repeat. For example, the markup for the gMapMarker test would look something like this:

<ace:gMap id="gMapMarker" style="width: 675px; height: 500px" latitude="0" longitude="0" zoomLevel="3">
	<ui:repeat value="#{gMapMarkerBean.markerItems}" var="markerItem">
		<ace:gMapMarker latitude="#{markerItem.lat}" longitude="#{markerItem.lon}" />
	</ui:repeat>
</ace:gMap>

The items in the gMapMarkerBean.markerItems collection would be simple POJOs that store some of the attributes of the gMap* subcomponent, in this case latitude and longitude. The tests pass if the subcomponents are successfully displayed/applied on the map.

ace:gmapLayer
All browsers - Clicking on any of the links from this line "Relevant sections of the Google Maps API: Bicycling, KML, Traffic, Transit" opens the google API in the same page as the showcase demo.
FF 33 - Navigating back to the demo causes a console error. Demo still functions.

ace:gMapInfoWindow (all browsers)
When entering input for window 4, the input persists into windows Five, Six and Seven.
To reproduce
Navigate to ace:gMapInfoWindow > Overview
Select the "Four" radioButton.
Click the marker to display the window.
Use the input field to enter some new text.
Press submit.
The text you entered will now be visible in the window.
Press the "Five" radioButton.
The text you entered into "four" will also be displayed in the window for "Five", "Six" and "Seven".

Those last issues were unrelated to these changes and were fixed under ICE-10379.

Porting these changes to the 3.3. EE maintenance branch is still pending.

r43351: added support for ui:repeat to all gMap* subcomponents in the 3.3 EE maintenance branch.

Please test in the same way as for 4.0.

All the issues above aren't related to this fix and aren't exclusive to ui:repeat, as they also occur when using c:forEach or simply using multiple tags explicitly. The issues with ace:gMapInfoWindow and ace:gMapOverlay have already been fixed at revisions 43805 and 43806 in the 4.0 trunk and 3.3 EE maintenance branch; the fixes for the other two issues are in progress.

Attaching gMapMultipleLayers.xhtml test page.

This test page can be added to QA's test app to see how Google just doesn't support displaying multiple layers at the same time. Therefore, we can say that the issue number 1 above is invalid.

In the test page I created a GMap using Javascript only (i.e. no use of any component; the Google Maps API was directly invoked). There you can see that if you have 2 or more layers in a map, only one will be displayed. It's impossible to display multiple layers at the same time, even if they are of the same kind. When, only one layer is declared, then, it is displayed correctly (if the current location supports it).

Attaching gMapMultipleServices.xhtml.

A similar test was made to test multiple services. It was found that Google Maps does support displaying multiple services on the same map, as shown in the attached test page, but this is currently not supported on our ace:gMap.

ICE-10459 was created to fix this specific issue.
