Tomodachi

- Messages via SNS+SQS or AMQP over 60000 bytes as JSON will now be sent in a gzipped base64 encoded format to allow for larger limits and lower potential SNS costs due to multiplexed messaging.
- Fixes an issue with multidict 3.2.0 on hot-reload which made the tomodachi application crash.

- Possibility to requeue messages that result in specific exceptions. Exceptions that will nack the message (for AMQP transport) is called `AmqpInternalServiceError`. Exceptions that won't delete the message from the queue and in turn will result in it to "reappear" unless configured non-default (for AWS SNS+SQS transport) is called `AWSSNSSQSInternalServiceError`.

- Corrected an issue regarding crontab notation for scheduling function calls where it didn't parse the upcoming date correctly if both isoweekday and day part were given.

- Catches unintended HTTP exceptions and prints a useful stacktrace if log_level is set to DEBUG.

- Fixes an issue where Content-Type header couldn't be specified without charset in HTTP transports.
- Cleared some old debug code.

- Corrects and issue with AMQP transport which caused invoked functions to not be able to declare scope variables without crashes.
