* Web: add support for the POST HTTP method.
This patch adds support for POST in addition to the already supported GET.
This is needed for implementing more complex web modules that also
support configuration modifications and advanced queries.
* Base web: return METHOD_NOT_ALLOWED when method isn't implemenetd.
