Add iter() and values() functions to PrimaryMap and EntityMap.

Browse Source 
`iter()` iterates over both keys and values, while `values()` iterates over
just values. Also add `_mut()` versions.

These replace the otherwise common idiom of iterating with `keys()` and using
indexing to get the values, allowing for simpler code.
