Use Zxing library for QR code reader & creator

Currently, we are using "QRDroidServices", by DroidLa. for creating & reading the QR code for Share Contact

Steps to reproduce

• Go to navigation drawer. Select Travel
• Go to Utilities. Select Share Contact
• For “QRDroidServices”, we need to download another app.

What to do?

• Use google’s Zxing library for creating as well as reading the QR code.
• Remove the code of “QRDroidService”

There are 2 buttons on that page:

1. Share my contact: The purpose of this is to share your contact via qr code. So, a qr code is presented on the screen (as well as placed in the gallery)
2. View someone’s contact: This opens up a scanner, can read that particular qr code, decodes it & saves the person’s contact (name, phone number) in user’s contact list.

Earlier, we used to have phone number also in the login/signup process. But now it is replaced by email ids. So, replace the phone number also in qr code with the email id.

We can save email id also in contacts. Do that
