Title: Add ability to specify columns for multiget queryColumns

ColumnFamilyTemplate has a queryColumns method for a single key where you can specify which columns to return.

public ColumnFamilyResult queryColumns(K key, List columns)

There was no multiget equivalent though i.e:

public ColumnFamilyResult queryColumns(Iterable keys, List columns)

Only a method that requires you use a ColumnFamilyRowMapper:

public MappedColumnFamilyResult queryColumns(Iterable keys, List columns, ColumnFamilyRowMapper mapper)
