changed: the functions getCreateMyGridPage and ajaxCreateGrid in
gridMng/views have changed. The ajaxCreateGrid only returns a xml
response with a div containing an empty grid, it no longer calls the
getCreateMyGridPage function. The getCreateMyGridPage function now only
returns
the html code for the entire page that is used by the user to create a
(private) new grid

added: new url in the gridMng/urls files, the new url (grids/createPage)
is used to point directly to the getCreateMyGridPage. (show the grid
creation page)

changed: the in place link points now to grids/createPage

changed: the createGrid function in createMyGrid.js does pass the
tableOnly argument anymore

changed: added more and better comment to getCreateMyGridPage and
ajaxCreateGrid in gridMng/views.py
