* Replaced GtkWindow by ModestWindow in some places

	* Replaced GtkWindow by ModestWindow in some places
	* the refresh operation now calls the user callback even if it fails
	* fixed some errors in the open_msg action in the UI actions, it was not opening the cached messages when the account was offline
	* Added the TnyAccount parametter to the connect_to_get_msg private func
	* Removed some warnings in the code
	* Fixed an unref
	* Fixes NB#66769, now we wait for the account to be connected before trying to open a message. In order to do this I had to rewrite the modest_platform_connect_and_wait
