Client Codegen doesn't handle the name properly with play projects.

[paulpdaniels]

Currently the client codegen uses a regex based system to extract the name of the client from the file name (or falls back to Client if it can't find it). The regex however relies on the presence of /scala in the path name which breaks with play (and any custom directory structures).

Work around is to make your client projects part of a separate module if using play (one that follows the correct directory structure). But given that play is pretty widely used it seems like we could support it out of the box since it is just about adding a |play to the regex.

Sure, let's add |play 👍
