Travis-CI status in readme needs to be for master branch and ammending commits when necessary

Hi @ivanlanin ,

I would have sent you this by email but I do not have your address, maybe you can get in touch with me by email so I can add you to my contacts.

I will revert your changes to the develop branch concerning the travis-ci status in the readme that now gives the status of the develop branch instead of the master branch. There is really no point in having the develop branch status in the readme as it is not relevant for users using PHPWord and might be from time to time on the "Build fail" status while the master branch should always be on the "Pass" status.

Also, I wanted to take the time to tell you about amend commits that allow you to make 1 commit for a change instead of 4.

Hi @gabrielbull. I've sent you an email.

Ok, I think you're right. We should display the status of the stable branch.

Thanks for the info about amend commits. I'll do it next time.
