remove fortytwo.net that will not be used anymore for dependencies and remove aduna-snapshots that will not be used anymore

in future, sesame snapshots will be at sonatype, and releases will be at maven central, so these are not necessary anymore
remove deployment profiles that are not used anymore
bump versions and add url for developer
add fortytwo.net back in, as the rdfjson resource jar is not available otherwise
add prerequisites to specify maven-2.2.1 as the minimum
update versions for plugins and commons io and jog4j
