Reorganized naming table to remove ambiguity

[bkoelman]

As proposed in #131. Also:

• removed local constant, because casing is the same as a regular local variable.
• more high-level to low-level ordering, where not causing conflicts
• changed Enumeration to Enum (should be Structure instead of Struct otherwise)
• changed "enum values" to "enum member" (singular)
