Enhancement suggestion: namespace title in sidebar #148
Description
nspages has the "-h1" option to display the first "h1" for each page in the namespace.
The "-tree" option gives a nice vertical listing.
But in the sidebar, the namespace itself is listed as the raw name.
Enhancement suggestion: For nspages in the sidebar, add an option (e.g., -ns_h1) to look in the "start" page (that is, the default namespace page name), and display the first h1 title found. If the namespace doesn't contain a default page, or if the default page doesn't have an h1, then use the raw namespace name.
