/**
* Set default theme options.
*
* This function updates the theme options with the specified defaults ONLY if they don't exist. The
* idea being that new theme options can be added by a developer and picked up by the theme without having
* to blank the existing theme options first. If some options exist then merge current options with defaults
* to set any new theme options that may have been added since last theme activation. This method does NOT
* overwrite any theme options if they already exist.
*
* Important: Any checkboxes you need to be ON by default just add them to an array, in addition to the
* $pc_default_options array, but with a "0" value. Otherwise when the theme is deactivated/reactivated the ON by
* default checkboxes will always be set to ON even if the user set to off in the meantime. This is because if
* a check box is turned off it is not stored in the options db at all, but to be efectively tested by the
* array_merge($pc_default_options, $current_options) function, if it has been turned off by the user then it
* needs to be set to zero manually in the code.
*
* @since 0.1.0
