Revision 669318

HBASE-487 New shell....
Add in special handling of .META. table that we used have in HQL
(so it prints out the HRegionInfo pretty).  Also allow making a scanner
without specifying columns.

M  src/java/org/apache/hadoop/hbase/HTableDescriptor.java
   Allow getMetadata work if HTable is set against meta tables.
   Was failing on isLegalTableName if name was one of the catalog table names.
   Needed by shell.
M src/java/org/apache/hadoop/hbase/client/HTable.java
  Comment.
M  bin/hbase
  Remove commented out line.
M  bin/HBase.rb
  Allow passing just a table name to scanner; let it figure out all families
  Added in the special handling of .META. table cells that we used have in HQL
  so we can see start/end row, etc.  Added in extra testing.
M  bin/Formatter.rb
  Allow setting width of emitted table in console formatter
M  bin/hirb.rb
  Allow setting width of emitted table in console formatter
  Improved scanner help.:
