* Sets the session variable for custom colour schemes (1)
|
|
*
|
|
* This page accepts the required colour scheme as an argument, and
|
|
* sets a session variable accordingly. If the colour scheme is 1 (the
|
|
* theme default) the variable is unset.
|
|
* If the page is being requested via AJAX, we just return HTTP 200, or
|
|
* 400 if the parameter was invalid. If requesting normally, we redirect
|
|
* to reset the saved setting, or to the page we came from as required. (2)
