Started to lighten up AGDISTIS in order to facilitate deployment and maintainance.

 * deleted sql dumps
 * deleted log dumps
 * deleted NER, DB adapters
 * deleted AIDA

GOAL: AGDISTIS will be a easy-to-deploy, agnostic-of-the-knowledge-base Named Entity Disambiguation/Linking tool

=> Evaluation will be done with the BAT-framework from Cornolti et al.
Deleted database functionality and judgement agreement
 * deleted data base java classes
 * deleted judgement agreement class
 * deleted leftovers from AIDA and the uber topicmodelling

GOAL: Future experiments using AGDISTIS should be performed on another project
Clean up of unused elements in pom.xml
Updated Test classes. Especially deleted Spotlight test in order to achieve maintainability
Deleted classes to test and evaluate other spotters
Removed datasets for experiments and several experiment files in order to adjust for new light AGDISTIS without compromising its scalability or accuracy
 * removed datasets since they can be found in N3 collection or BAT-framework
 * removed experiments from this branch since thex can be found in git history and this experiments do not contribute to AGDISTIS deployment

Please have a look at commit #80 for full-experiments on AGDISTIS.
Shrinked datatypes to useful part
Organize imports after deletion rage
Corrected testcase
Cleaned the pom.xml a bit more to resize AGDISTIS
Cleaned up pom.xml.

It contains now only dependencies that are really needed and is thus more performant at checkout.
Cleaned up logging behaviour.
Started to convert all Strings to properties in order to facilitate easy maintainability of AGDISTIS.
Pushed Index Creating towards using configurable properties.
Index position will now be loaded via agdistis.properties.

 * During cleanup imports were organized and each file has been formated accordingly
Refactored the SPARQL endpoint class in order to be more concise.
Refactored graph package.
Refactored CandidateUtil in order to facilitate use of agdistis.properties
Removed the last strings from java string and moved them to the agdistis.properties fiel.
Refactored exception handling. Now either AGDISTIS does not boot or while working on a document an exception is thrown.
