unable to _return_ language strings after already loaded

Applies to CI v1.5.4

Once a language file has been loaded, the CI_Language::load() function will no longer honor the $return parameter to simply return the language strings.

Lines 56-59 of CI_Language::load():

Code:

if (in_array($langfile, $this->is_loaded, TRUE))
{
    return;
}

That code should also check the $return parameter rather than just halting.

Reproducible steps:

1. Load a language file normally.

Code:

$this->lang->load('some_category', 'german');

2. Attempt to get the values stored in the same language file:

Code:

$some_strings = $this->lang->load('some_category', 'german', TRUE);

The TRUE would no longer be honored since the file had already been loaded once.
