Source/WebKit2:

The Ewk_View now reports the estimated load progress
of the page via the new "load,progress".
A method is also added to Ewk_View in order to
retrieve the current load progress.

* UIProcess/API/efl/ewk_view.cpp:
(ewk_view_load_progress_get):
(ewk_view_load_progress_changed):
* UIProcess/API/efl/ewk_view.h:
* UIProcess/API/efl/ewk_view_loader_client.cpp:
(didChangeProgress):
(ewk_view_loader_client_attach):
* UIProcess/API/efl/ewk_view_private.h:

Tools:

Update EFL MiniBrowser so that it listens for the
"load,progress" on the Ewk_View and updates its
window title accordingly.

* MiniBrowser/efl/main.c:
(title_set):
(on_title_changed):
(on_progress):
(browserCreate):
