Implement "maniphest create" command

[Grokzen]

Add new command maniphest create to the maniphest app

This only supports a very small subset of all available options and arguments that can be set on the ticket itself to keep things simple. No hiearchy or ticket linking posible for now, but maybe addition in the future if we really need it. For now any linking between tickets has to be done manually after the create

Example output after running the new file test-template.yaml included in the PR

Closes #52

Example debug logging output when doing a --dry-run
