[mapguide-internals] MapGuide RFC 80 is updated.

[Leaf Li]

All,

I update MapGuide RFC 80. Can you review it?

The original solution is to add two new overloaded method ExecuteSqlQuery and ExecuteNoSqlQuery to support parameter binding. The current plan is to extend method ExecuteSqlQuery and ExecuteNoSqlQuery added in MapGuide RFC 78 because those two methods isn't released yet.

Thanks,
Leaf Li
