This needs a rebase

git pull --rebase upstream master
git push origin documentationFeature -f

-f for force push, as there is change in history.
This time I'm writing out the specific commands, next time onwards you would know what to do when I say rebase :)

[ritzvik]

After this ready for merging

@OVSofia
Also, kindly learn what is squashing commits.
https://github.com/todotxt/todo.txt-android/wiki/Squash-All-Commits-Related-to-a-Single-Issue-into-a-Single-Commit

Not this time, but I might ask you to squash commits sometime in future.

Thanks

[shreyasbapat]

I will ask you to do one more rebase :)

I will merge some PR's before this one :/
Sorry for the trouble!
