Commit 61a50b9e authored by Jon Skeet's avatar Jon Skeet

Change how the reflection descriptor class is generated.

Instead of having a Proto nested namespace to avoid conflicts between the descriptor-holding static class and message classes, just append "Reflection" to the name.
Generated code changes (and corresponding manual changes) in following commit.
