Added Eclipse files to gitignore, updated & formatted readme

[szarnyasg]

Besides the cosmetic changes, the main enhancement was to update this command

cp target/import-tools-2.2*.jar target/dependency/opencsv-2.3.jar target/dependency/neo4j-geoff-1.7-SNAPSHOT.jar target/dependency/mapdb-0.9.3.jar /path/to/neo4j-community-2.2.5/lib

Following zip.sh, I

• removed the "2.2*" version string
• added kryo, reflectasm and objenesis
• changed neo4j-geoffjar to geoffjar

Thanks a lot.
