Sending emails using gmail

[GaelleMarais]

Hi. @LilyaMel and I have been working on including a way to send emails using gmail. ( cf issue #18 )

I am using the OpenSSL package (libssl) to create a secure socket, wich is mandatory for communicating with the gmail server:smtp.gmail.com

In order to compile the project you need to add -lssl -crypto -lto gcc. Consequently, the full command to compile the project is gcc main.c $(pkg-config --libs --cflags libcurl) -lssl -lcrypto -l json-c -std=gnu11

I added the new command in the README.md file and in the .travis.ymlfile. You also need to installopenssl (ubuntu) orlibssl(fedora), command installations are on the README.md file.

What we have modified:

• analysis.c ,request.cand response.c: add email_score to manage email-related sentences such as 'Can I read my emails?' or 'I want to send an email'. -.travis.yml: update the compilation command.
• README.md : update the compilation command and add the installation of openssl(fedora)/libssl(ubuntu) -help.txt : add the email command. -main.c: include email.c

What's new :

• email.c: Main file to manage email requests.
• ssl.c : A file to create a secure socket layer and communicate with gmail servers.
• b64.hand b64.c : A file to encode/decode word in base 64, needed for encode email adresses and passwords.
• config_email : A temporary file where we stock the encoded email adress and password.

Note: We are currently working on a way to read emails and we will make another PR for that.

I hope our work will interest you and that you will accept this PR. If you have any questions I'll respond as soon as possible. Thank you

Hello, thank you for your reviews. I have made the requested changes.

@ritwik12 Have you activated the parameter "Allow access to less secure apps" in your google account ? If it is not activated, only official applications made by Google can access your gmail account. I explained how to do it in the README file.

It you have activated it and it still doesn't work, I have to know if the problem comes from your gmail account or your device. Can you try again with this account I created especially for testing purposes :

id: mangabountynaia@gmail.com
pwd: MANGABOUNTYNAIA

[ritwik12]

@GaelleMarais I have tried using the account given by you. It isn't working. Let me recheck.

[GaelleMarais]

In file ssl.c can you uncomment all lignes marked with DEBUG and show me the error messages?

[GaelleMarais]

@ritwik12 Any news ?

[ritwik12]

@GaelleMarais Sorry, I got busy. Let me check

[ritwik12]

@GaelleMarais Code is great. Works well. Thanks for contributing such a great feature.

[ritwik12]

@GaelleMarais We need one more section in README for Email feature to explain it's working with screenshot just like we have for all other features. Would you like to do that?

[GaelleMarais]
