format required for
processing by the sapi handlers. They create an array called $_POST['weaverx_main_settings']. Each
setting in that array corresponds to a Weaver Xtreme option value, and will be passed to the
validation function.
We will wrap the main form (Main Options) with our functions
weaverx_sapi_form_top() and weaverx_sapi_form_bottom() that generates required calls to sapi.
All other forms will use submit buttons that include their own nonce definition. Other forms generally
do not change individual settings, but take actions such as save/restore or setting a subtheme.

In reality, we really only need to register one setting - 'weaverx_main_settings_group',
and the settings will be saved in the WP DB as 'weaverx_main_settings'. The SAPI uses
the name param of any fields to figure out where to store the input value.
The validation will have to scan the ENTIRE list of options and lookup the kind of
validation each parameter needs.
NOTE: This code is here to support Legacy Weaver Xtreme Theme options settings.
Version 2.0 does not use or call these validation functions directly, but the are needed
to support the legacy options interface.
