Subject: [E-devel] [Patch][elm_map] Apply elm gesture

elm_map implement pinch gesture by using evas mouse event. But it made
codes too complicated and dirty.
So I have changed pinch gesture by using elm_gesture. wheel zooming is
also improved somewhat.
From now on, configuration change related elm_gesture easily applied
to elm_map and we can see more smooth zooming :D

Anyway, els_scroller have bugs when the scrolling event & the resize
event occurs at the same time.
So, some dirty codes are added for preventing jumping to strange positions.
Later it will be removed when the bugs are fixed.
