Add more standard cursors

Browse Source 
This adds the standard cursors for diagonal and omnidirectional
resize/move and operation-not-allowed.  It also adds new (better?) names
for the horizontal and vertical resize/move and pointing hand cursors.

GLFW uses both the Xcursor extension and the freedesktop cursor conventions to
provide an expanded set of standard cursor shapes. If the running X server does
not support this extension or the current cursor theme does not support the
conventions, the `GLFW_RESIZE_NWSE_CURSOR`, `GLFW_RESIZE_NESW_CURSOR` and
`GLFW_NOT_ALLOWED_CURSOR` shapes will not be available and other shapes may use
legacy images.
