Commit .gitignore directly

Rather than relying on the cloner to copy the
provided gitignore.SAMPLE files.

This finishes the job started in c48509598, mostly
by reverting that commit and moving the two existing
SAMPLE files to the final destinations.

Use `.git/info/exclude` to augment the list of patterns
with entries specific to your workflow.
STARR: use 2.11.0-M4, built with 2.11.0-M3

Replaced starr jars with 2.11.0-M4, built with Scala 2.11.0-M3.

I used `ant replacestarr-opt -Dstarr.use.released=1`, with `starr.number`:

```
starr.version=2.11.0-M3
```

Then pushed the jars to artifactory after moving `lib/jline.jar` out of the way,
as it's no longer "desired" (i.e., not pulled from artifactory). Its presence
seemed to break `./push-binary-libs.sh $ARTIFACTORY_USER $ARTIFACTORY_PASS`.

You can by-pass the custom starr artifact download and use a (released) version
of Scala by changing your `build.properties` to include

```
starr.use.released=1
```

You may optionally change `starr.version` in `starr.number` to whichever version
that maven can resolve for you.
