[FLINK-1203] Use forked execution in all tests, except in the end-to-end integration tests in flink-tests

This closes #174

- Clean dependencies in flink-streaming connectors

  - add "flink-shading" for shaded libraries (currently guava only)
  - relocate guava in all projects and exclude it from the lib and exported dependencies
  - Exlude unnecessary transitive dependencies from hadoop 1

We'll still ship the Logback configuration file and pass them their path to the JVM so that
users can use Flink with Logback as well.

This closes #125

Checking for Java support

Small changes and meaningful exception for unsupported compilers

pom.xml modified to use JDT compiler

Project structure refactored, examples added

Documentation added

Quickstart adapted

[FLINK-1114] Move scala-style checks to scala projects, change paths to style conifg, to allow isolated building of individual projects.

I excluded all slf4j-log4j12 transitive dependencies to get rid off the warning that slf4j finds multiple slf4j bindings in the classpath. Additionally, I added log4j-over-slf4j and excluded all log4j transitive dependencies so that slf4j handles also legacy log4j logging messages from dependencies.

Closes #121 from tillrohrmann/FLINK-1097 and squashes the following commits:

b9f76d5 [Till Rohrmann] Excluded slf4j-log4j12 as transitive dependency in order to not have multiple slf4j bindings in the class path. Added log4j-overslf4j and excluded log4j transitive dependencies to collect log4j outputs.

- Excluded Kafka's transitive dependencies: jmxtools and jmxri
- Corrected encoder pattern in logback.xml
- Removed explicit logging access. Loggers are now configured by
  configuration files. Fixed Yarn issue with multiple logging
  bindings.

This closes #111.

Users using CDH4 can now build Flink against Hadoop 2.0.0-alpha.

- update _config.yaml of integrated documentation
- quick check on the quickstarts / build instructions to match the latest release
- quickstart.sh scrips now point to the correct versions.

This closes #72
