Missing POMs

    The POM for com.tinkerpop.blueprints:blueprints-sail-graph:jar:2.5.0-SNAPSHOT is missing, no dependency information available
    The POM for com.tinkerpop.blueprints:blueprints-graph-sail:jar:2.5.0-SNAPSHOT is missing, no dependency information available

Removed -SNAPSHOT from blueprints.version (so just 2.5.0) to resolve the above.
