LBSystem::is_disabled($text)

 Used for config parameters. Returns True if the $text contains a word that fuzzy could mean False.If the passed string contains one of these words:

false, no, off, disabled, disable, 0

The function will return True, otherwise False.

The keyword search is case insensitive.

This is not a inversion of is_enabled.

The intention of the is_disabled function is to query a config parameter for a feature that is normally enabled. If it is not explicitly disabled, you default to enable it.
