RFCs for next SPTK release

["Ilya A. Volynets-Evenbakh" <ilya@total-knowledge.com>]

Hey,
Here are few things that would be nice to have.

1. Namespace. Let's wrap all classes in sptk:: namespace
2. Some minor cleanups:
    a. make CBuffer.data() non-const (I think it's more or less illegal
       to return non-const pointer to member, from const function)
    b. Make it return void, not char*, since it is data buffer, not
        character buffer.

I'll continue this list, as things come to mind.
