Allow adding additional columns to ParseUser through the set call

[VigneshPasupathy]

ParseUser("DummyUserName", "******", "[email protected]")..set("userPhoneNumber", "123456789");

Currently ParseUser Signup only writes username, emailId, password to the User database and doesnt accept additional columns added through the .set(key, value) API even though the data is available in objectData.

Modifying the signup() code to accomodate for the same.

Hey Vignesh

Thanks for your contribution!

Is this tried and tested and all working? If so, please can you close this PR and open a new one but instead, create the pull request with the branch release/1.0.23? I'll merge it as soon as you put it through.

Thanks!

Hey,
I currently have a local copy of release/1.0.22 with this piece of code for another project of mine and the updates to Back4app work fine.
Do let me know if there are any specific tests you'd want to me perform for this code base

@VigneshPasupathy
Very good. I needed this, but no time to make this change.
@phillwiggins
do you have any plans to release this release?
I will try this week to validate with my test app.

[RodrigoSMarques]

@VigneshPasupathy
Please update the documentation (READ.ME) with this example.

[VigneshPasupathy]

Sure @RodrigoSMarques Will update and create a pull request against release/1.0.23

Closing in favor of #232
