MODSOFIA-92 Add openssl build support to windows - no external build support needed (step 1 - not hooked up yet) vs2008 pro+ only

[mod_commands,mod_event_socket,mod_event_test] fix up other users of switch_event_xmlize() to use SWITCH_EVENT_NONE

[mod_lcr] Use SWITCH_VA_NONE instead of an empty string to (finally) fix the gcc printf format warnings.

mod_callcenter: More ODBC changes.  It is not a global settings value.  Cannot be changed in runtime.

mod_callcenter: Add ability to unload/reload/load a queue setting (You still need to reloadxml before).
Note that joining a queue will check for it in the config and load it on the fly... I've used the same system as in mod_voicemail.  Not sure if we should allow this, but just comment it out of the config before unload and it wont be available anymore
