Properly formatting passed in serializer namespace

[antstorm]

This fix allows to pass namespace: :api, with a lowercase :api. Old format, of course, is still supported.

[antstorm]

Any chance of getting this in?

@antstorm I'm not sure that this really adds anything useful and it would kind of make things confusing if it were ever introduced into the Readme as such, because you could have more than one module in the namespace and there would be no way to present that if you pass in a symbol, right?

namespace: 'Api::V1'
# vs.
namespace: :api ???

[antstorm]

@saneshark sure, there's no way of specifying two or more nested modules in a symbol. My reasoning behind this change is to keep things consistent with Rails, which has namespace :api in the router, that is then used to prefix your controllers with Api::.

It might be hard to compare these two cases, because router does much more than just prefixes controller classes, but still I think that's a valid point.

We need more people chiming in here to make a decision.

This issue does not seem to have moved for quite a while. I'm closing it. If somebody like this should be re-opened, feel free to leave a comment.
