Create program namespaces

[priestc]

Currently all programs are under the same 'root' namespace:

# web
http://localhost:5000/multiply?x=5&y=4

Change it so you can easiely add namespaces, so programs with the same name can coexist:

# web
http://localhost:5000/math/multiply?x=5&y=4
http://localhost:5000/other/multiply?x=5&y=4

Do this by adding a namespace wrapper when defining programs:

class Math(GiottoProgramNamespace):
    name = "math"

    class Multiply(GiottoProgram):
        name = "multiply"
        model = (multiply, )
        view = (MultiplyViewer, )
        controllers = ('http-get', 'irc')

class SomethingElse(GiottoProgramNamespace):
    name = "other"

    class Multiply(GiottoProgram):
        name = "multiply"
        model = (multiply, )
        view = (AnotherMultiplyViewer, )
        controllers = ('http-get', 'irc')
