Click area extension option (for all obj)

[nagyrobi]

There's the lv_obj_set_ext_click_size function, which is very useful in case of narrow widgets like slider or arc, where you can loose the touch while dragging if you don't follow the widget precisely with your finger.

In OpenHASP it's implemented as a common property for any object as:
ext_click_h Extended horizontal clickable are on the left and right
ext_click_v Extended vertical clickable are on the top and bottom
which are 0 by default, positive integers.
