Patch: export more methods to python

[Anatoly Asviyan <aanatoly gmail com>]

Hello,

I needed some functionality exported to python from gnumeric for
a personal project, and it looks to me like something that might
be useful to others too.  Thus, here's the patch.

It adds the following methods to the python "Sheet" object:

* insert row
* delete row

and the following ones to the python "GUI" object:

* get sheet (current sheet)
* get cursor (active cell in a current sheet)

Now, it's possible to do something like this:

def insert_row(gui):
    s = gui.get_sheet()
    pos = gui.get_cursor()
    s.insert_row(pos.row)

The patch is here
