EnhancedGrid - Pagination: require to indicate page size and page number before grid is initialized

[elvis]

This is a requirement, the EDG pagination should allow user to indicate an initial page size/number before the grid startup.

DojoX Grid and EnhancedGrid are deprecated in favor of ​dgrid and ​gridx.

You should upgrade your code to use one of those two grids.

We will consider patches to the old DojoX Grid code though.
