Patch: more responsive header list model

[José Dapena Paz <jdapena igalia com>]

	Hi,

	This patch adds a new method to TnyGtkHeaderListModel, to allow to
change the behavior of the headers load, to be more responsive (and
slower.

	The new method is tny_gtk_header_list_model_set_update_in_batches(). If
TRUE (default option and previous behavior) it will load in batches of
3000 headers in notify_views_add.

	If FALSE, it will load in batches of 300 headers, so it will be more
responsive (allowing processing of events more frequently, more
incremental load of the data, etc).

Changelog entry:

	* libtinymailui-gtk/tny-gtk-header-list-model.c:
	new method tny_gtk_header_list_model_set_update_in_batches
	to change the way headers are exposed to tree model. If
	TRUE (previous behavior and default behavior), then it will
	load 3000 headers in each run. If FALSE, it will load 300
	headers in each run, so it will allow more processing of
	gtk events (and more responsiveness).
