Cute Selenium browser to conduct a random walk through the archive.

	pom.xml
Refactoring of Wayback/Warcbase integration points.
Merge branch 'selenium' into working
Minor tweaks.
Fixed issues #80 and #78

Issue #80: Close stream in WarcbaseResourceStore
Issue #78: Look into using Selenium to automatically navigate through the archive
Added @Override annotations to appropriate methods.
Added/refactored test cases for JWAT.
Added Hadoop bindings for webarchive-commons ARC readers, demo, test cases.
Very rough prototype of wrapper that allows interoperability between HBase table mappers and ordinary mappers over ARC files. Lifted mostly from ChainMapper implementation, code version in CDH 4.7
Minor refactoring.
Fixed issues #84, #72

Issue #84: Test cases for InputFormats (for ARC)
Issue #72: Implement Hadoop bindings for webarchive-commons (for ARC)
Implemented ArcRecordWritable.
Both the Jwat and Wac versions of ExtractLinks gives the same exact output.
Minor refactoring, revised counters.
Switched ExtractSiteLinks and InvertAnchorText over to WacArcInputFormat; link structure the same, anchor text results better due to switch from ISO-8859-1 to UTF-8 decoding of pages.
WacArcInputFormat now generates ArcRecordWritables.
Merge branch 'working' into table-wrapper
Refactored WacMapReduceHBaseWrapperDemo, now takes advantage of TableChainMapper to reuse mapper for HDFS ARC data.
Fixed issues #86, #85, #74

Issue #86: Move link extraction code over to using new WacArcInputFormat
Issue #85: Writable container for ARCRecord
Issue #74: TableMapper wrapper for interoperability between HBase vs. processing (W)ARC data
