We previously allowed a wide range of service names. As the service name is sometimes used to name databases, the name was actually more restricted than any character, resulting in services that wouldn't start. Going forward, only alphanumeric and underscore characters are allowed. This only impacts service creation. Any services with invalid names should be migrated to a new service, with the data exported and imported as normal. Closes dokku/dokku-redis#99 Closes dokku/dokku-mysql#47 Closes dokku/dokku-mongo#86 Closes dokku/dokku-redis#81
