[mapguide-internals] [Code Review Request]: Please Review the patch for Ticket 1193

[Buddy Hu]

Hi list,

I've attached a patch for ticket #1193, please review it: https://trac.osgeo.org/mapguide/ticket/1193

Some comments:
[Problem]
Select-within causes a 500 Internal error in the browser, when select multi features(including polygon and other types).
There are some logic errors in the selectwithin.php (jsp and aspx have the same problem). It uses the type of the first feature as the type for all the other features. If the first feature is a polygon, it adds all features into a MgPolygonColloection, then 500 Internal Server error happens.
The fusion has same problem.

[Solution]
Get the type of all features, if it's not polygon, we will break. Because, the Select-within only works for polygon.

Regards,
-Buddy Hu
