The code for page creation from menu edition dialog was there but
invisible to the user because of a wrong qweb template inheritance.
Indeed, the edit menu dialog relies on an extension of the link dialog
template. But this one is extended in-place in another location and
that extension is not considered when the second extension is made
because a t-extend always use the base template. The only solution to
achieve the same result is to copy the edit menu dialog qweb extension
in Javascript.
Note: the feature was still available from the link dialog in page
edition though because this was not concerned by the wrong qweb
extension.
However, adding a page by this way would create multiple pages because
one was created each time a page name was entered (and not only on
save !). So typing "test", then changing its mind and typing "hello",
then rechanging to "test", then hitting the save button created the
"test, "test-1", "test-2" and "hello" pages.
This fix takes advantage of an already present parameter which can
determine if a new page should be created or not. However, a code
refactoring should be done in master for these classes.
