Document the plan of changing naming conventions for namespaces

Namespaces are from now on planned to be in snake_case instead of
UpperCamelCase. This is of course entirely due to cosmetical reasons,
but I feel that it maps better to the upcoming changes in directory
structure where I don’t want camel-case directory names.

 Please follow these conventions:
 
-* Use `UpperCamelCase` for types (e.g. classes and structs) and namespaces.
-* Use `UPPER_CASE` names for macros and (non-class )enum values.
-* Use `snake_case` for other names (functions, variables, enum class values,
-  etc.).

+* Use `UPPER_CASE` names for macros and (non-class) enum values.
+* Use `snake_case` for other names (namespaces, functions, variables, enum class

 * Use an `m_` prefix for non-public member variables.
 * Use a `g_` prefix for global mutable variables.
 * Use a `k_` prefix for global constants.
