Added deployment settings for multiple component record

If there's a setting like 
<pre> settings.cms.multiple_organisations = True </pre>
then the function definition should be like this
<pre> def get_cms_multiple_organisations(self): </pre>
and not
<pre> def get_cms_multiple_organisation(self): </pre>
Notice the 's' after organisation( 's' is there in the variable name so it's included in the function definition as well ).
This is a convention being followed ;)
