prevent segfaults when no document loaded1.20

See the issue report for a description of the bug. The root cause is
dereferencing of NULL pointers, specifically the priv->document member of
EvWindow structures when no document is loaded. This commit adds checks
for a NULL value of priv->document at all the points in the file
shell/ev-window.c where this pointer was previously dereferenced without
being checked.
