added files to be ignored by .gitignore

[giovannivelludo]

I was having problems with loading project settings on my machine, adding these files to .gitignore (which were ignored in our group's projects) seems to have fixed the issue.

[CremaLuca]

Interesting, how does ignoring two modules files fix the problem? Is there a known reason or just straight magic?

Also i'm declining the other pull request to update gradle because it's also on this one.

[CremaLuca]

All ok, I don't fully understand why but seems reasonable

[CremaLuca]

Seen it also in https://gist.github.com/iainconnor/8605514
Might be a good thing to do then

@CremaLuca All I know is that Marco used a gitignore suggested by GitHub when he created the repository, while the gitignore we had in our group project was generated by Android Studio. I'm guessing the second way is better because the way Android Studio works changes with updates, and GitHub might not be always up to date with Android Studio changes.

Yup, we can either let android studio create it's own, or use the one in the link @CremaLuca posted.
What would you prefer? I'd use the one of the link

[Cogno-Marco]

Also if this problem is here, then it's also in killer-app and network-dictionary

[giovannivelludo]

I think we should use the one generated by Android Studio since we don't know if the one linked above will always be up to date.
Please don't merge this pull request until I remove the files I added to .gitignore, which I figured out is not done automatically by git.

[giovannivelludo]

Ok, now the pull request can be merged.

[Cogno-Marco]

Yup, seems fine to me too 👍 ready to be merged

[giovannivelludo]

Merge it then

[Cogno-Marco]

Was waiting for @CremaLuca to see, seems there's no reason to wait so I'll merge myself
