Remove delimiter boolean logic

The boolean logic in the delimiter was causing an error.  
In the original FuelPHP class, it's checking for a delimiter either 
passed into the method, or in the config.  Since the delimiter is 
now passed through the attributes array, the 'or' can't find 
a default '$delimiter' and throws a undefined variable error.  
The array get checks for the delimiter in both the attribute array
and the config array, so it's safe to remove.

Converts our booleans to integer values so that they are not converted
to blank values when processed.
Added check to output an empty array before failing with no data exception.
