Ability to use where() method

[Cannonb4ll]

Related issue: #7

This PR allows the usage of a basic where() method to be able to filter on tenants for example.

Code example:

\App\User::search('a')->where('tenant_id', 1)->get();

You can chain multiple where's, it currently applies the AND statement if you add more than 1 where method.

Single where URI:
?q=a&filters=tenant_id%3D1

Multiple values:
?q=a&filters=tenant_id%3D1+AND+name%3DHi+AND+email%3Dtest%40example.com

Good work @Cannonb4ll
The only problem is the $value must be escaped by ".

NOTE

string values are either double-quoted, single-quoted or a single unquoted word: title = "Scream", >title = 'Scream' and title = Scream are all valid syntaxes, title = The Avengers is not.

Example of error I get when using where('foo', 'bar baz');
filter parsing error: parsing error on line 1 at column 15: expected other, AND, or OR
