This PR adds this directory into the Python default
gitignore. See
https://github.com/pypa/pip/blob/e5f4bbb7ddff87f48f2b5815513e4211ccdde83a/src/pip/_internal/req/req_install.py#L568

Update Ruby.ignore to ignore .byebug_history file

The file `.byebug_history` is generated when using the popular https://github.com/deivid-rodriguez/byebug gem for debugging in Ruby. It contains a list of commands the user has run while debugging, which should not be committed to the repository. The author of the gem agrees with this here: https://github.com/deivid-rodriguez/byebug/issues/204#issuecomment-178238302

Unity: ignore mdbs, fix path to crashlytics file, make AssetStoreTools optional

Only people building Unity plugins will need to import the asset store tools plugin into their project, and it's a toss up whether they want to commit the tooling into their repo (they might or they might not want to, it highly depends on their workflow). The default .gitignore shouldn't be making this choice for these users.

Unity projects targeting the 2.0/3.5 runtime or built with mono < v5.0 generate `mdb` files, not `pdb` files.

Looks like the `crashlytics-build.properties` gets around in more than just the `StreamingAssets` folder, looking at [examples around the internets](https://github.com/auth0/sharelock-android/blob/master/app/src/main/assets/crashlytics-build.properties), so it should probably just be ignored as a filename.

google-services.json

vcs.xml can be considered for gitignore as per this [stackoverflow discussion](https://stackoverflow.com/questions/16736856/what-should-be-in-my-gitignore-for-an-android-studio-project/18454251#18454251)

google-services.json file should be commented on default if they want they will change otherwise it'll destroy the project
