Created ability to query specific colums

[jvskelton]

See #90.

Modified .all method to accept attributes property to select single or multiple columns.

Example 1:

model.all({where : {name: 'bill'}, attributes: 'id'}}, callback)
OR
model.all({attributes: 'id'}}, callback)

returns array of ids (e.g. [ 1, 2 ]):

Example 2 :

model.all({where : {name: 'bill'}, attributes: ['id']}}, callback)
OR
model.all({attributes: ['id']}}, callback)

returns array of objects(e.g. [{id: 1}, {id: 2}]):

Example 3:

model.all({where: {address: '123'}, attributes: ['id', 'name']},callback)
OR
model.all({, attributes: ['id', 'name']},callback)

returns [{id: 1, name: 'bill'}, {id: 2. name: 'alice'}]:

should be replaced with .all

@anatoliychakkaev https://github.com/anatoliychakkaev just a heads up:
with the recent changes to jugglingdb core, this will also require some
modifications to adapter.all, specifically, the functionality that returns
an array of data vs array of objects (depending on the attribute
type(string vs array)
