#25670: update_option() values persist even when no longer exist in the code

 The default WordPress' behaviour is to store the `update_option()` values
 to the database. Thus, if an option was once updated it will keep the same
 value forever, even after the theme author or mantainer removes
 `update_option()` from the code. This can lead to difficulties when
 debugging issues related to options, because even if in the actual code no
 option's value is being updated, the once set value will still run.

 '''Expected behaviour'''
 Only when an `update_option()` is passed in the actual code should its
 value apply. Otherwise, the default value should apply.

 '''Proposed solution(s)'''
 1 - Instead of permanently storing options in the database, only do it as
 longs as `update_option()` it's in the code. Otherwise, set the value back
 to the default.
 2 - Set option values only at runtime, without any database storing.



 PS: Hope my english is good enough ;-)
