Add email support, update .gitignore and .env_example (#10)

**Add email support for video summaries**

This PR allow us to send video summary results via email instead of printing them. It also updates .env_example so that the template for environment variable is up to date.

**Note:**
Due to limitations with my OpenAI API token (insufficient credits), I was only able to successfully test the email sending independently. Integration of email with the transcription and summarization output has not been tested.

**Closes #9**
