Title: Support "mvn test"

- Lets maven run OpenTSDB unit tests.
Modifies pom.xml.in to configure the surefire plugin properly. Also creates
plugin_test.jar that some unit tests depend on.

- Makes it easy to use Eclipse.
The steps for OSX will be:
0. Install OSX autoconf
port install automake autoconf libtool
1. Generate pom.xml and the Eclipse-friendly directory structure overlay
./build.sh pom.xml
2. Build the maven project
mvn clean compile
3. Import the Maven project into Eclipse.
4. Include target/generated-sources in Eclipse source path.

- Added some file extensions and working files to .gitignore.

NOTE: Squashed multiple commits into one, and kept the original descriptions.
