===============================================================================
                                PopUp plugin
Plugin Name: PopUp
Plugin authors: Luca Santarelli aka hrk (hrk@users.sourceforge.net)
                Victor Pavlychko (nullbie@gmail.com)
===============================================================================
The purpose of this plugin is to give developers a common "platform/interface"
to show PopUps. It is born from the source code of NewStatusNotify, another
plugin I've made.

Remember that users *must* have this plugin enabled, or they won't get any
popup. Write this in the requirements, do whatever you wish ;-)... but tell
them!

NOTE! Since Popup 1.0.1.2 there is a main meun group called "PopUps" where I

by adding these lines before you call MS_CLIST_ADDMAINMENUITEM:
mi.pszPopUpName = Translate("PopUps");

Otherwise, it can return anything else...

You may pass additional creation flags via lParam:
	APF_RETURN_HWND ....... function returns handle to newly created popup window (however this calls are a bit slower)
	APF_CUSTOM_POPUP ...... new popup is created in hidden state and doesn't obey to popup queue rules.
							you may control it via UM_* messages and custom window procedure (not yet implemented)
	APF_NO_HISTORY ........ do not log this popup in popup history (useful for previews)
	APF_NO_POPUP .......... do not show popup. this is useful if you want popup yo be stored in history only
	APF_NEWDATA ........... use new version of POPUPDATAEX/POPUPDATAW structs

   1. Event is fired with NotifyEventHooks in the main thread

   4. Miranda core *INSIDE YOUR THREAD* calls EnterCriticalSection(csHooks) and
      waits for main thread to finish processing
   5. Main thread calls SendMessage(hwnd, ...) to notify your window
