A first draft for a gnupg brute force application

* It provides a GnuPG interface
* A runner-framework for concurrent bruteforce processes.
Changed the build of the GnuPG bruteforce project

1. An ANT build helps for an overall code analysis with jacoco and
 sonar (ut + it analysis)

2. Still remaining problems: failing unit tests (in case of
 GnuPGIntegration(Test) a real performance test has to be made,
 integration tests have to be improved, cli implementation missing; and
 so on and on
Support for MAVEN and ANT; tests were improved

1. build.xml can be found in folder 'build'. It generates all files
 into directory 'target'. Maven is still using the pom.xml in the root
 directory.

2. This commit adds tests or improved tests. However, at least three
 tests are still failing or throw errors. Two errors are about timeout
 while the third one fails because of an assertion error.

What is missing?
	1. A stable listener principle between the running threads
	2. A stable command line interface with a valid and stable API (parameters)
	3. The single responsibilty pattern is still not appropiate
