Add two apis to limit page size of gengrid's scroller : elm_gengrid_page_relative_set and elm_gengrid_page_size_set. 

These functions work exactly as those in elm_scroller.

/**
* Set gengrid scroll page size relative to viewport size.

* The gengrid scroller is capable of limiting scrolling by the user to "pages"
* That is to jump by and only show a "whole page" at a time as if the
* continuous area of the scroller content is split into page sized pieces.
* This sets the size of a page relative to the viewport of the scroller. 1.0 is
* "1 viewport" is size (horizontally or vertically). 0.0 turns it off in that
* axis. This is mutually exclusive with page size
* (see elm_gengrid_page_size_set() for more information). Likewise 0.5
* is "half a viewport". Sane usable valus are normally between 0.0 and 1.0
* including 1.0. If you only want 1 axis to be page "limited", use 0.0 for
* the other axis.
