Consistent REST field spelling

[waterstorm]

The REST API field spelling should be consistent and not vary in terms of capitalized letters.

As an example the contacts CRUD actions:
- Create
- Retrieve
- Update
- Delete

Create, retrieve and update are using initial capital letters, for example the field success:
"Success"

In contrary Delete is using small letters:
"success"

This problem is applicable to a lot of different objects. Another example:
"Accounts -> Get account" returns everything in small letters, while "Account -> Retrieve account" returns everything with an initial capital letter.

This makes it more difficult to work with case sensitive REST API framworks/libraries such as Java GSON. Instead of doing the serialization once, one has to do it twice, just because of the capital letters.

@waterstorm, good point, we're looking to straighten this out.
