I added default forms and form names.

A PokeAPI/api-data refresh has started. In 45 minutes the staging branch of PokeAPI/api-data will be pushed with the new generated data.

The staging branch will be deployed in our staging environment and you will be able to review the entire API.

A Pull Request (master<-staging) will be also created at PokeAPI/api-data and assigned to the PokeAPI Core team to be reviewed. If approved and merged new data will soon be available worldwide at pokeapi.co.

The updater script has finished its job and has now opened a Pull Request towards PokeAPI/api-data with the updated data.

You can see the Pull Request deployed at our staging environment when CircleCI deploy will be finished (check the started time of the last build).
