Clean up blog code (particularly the www side).
Make `blog_load` return a ptr_vector which is consumed by the code that uses blog entries. Greatly clean up WWW page generation by using stralloc and strftime and the ptr_vector infrastructure. Needs to be tested. :-) Signed-off-by: Dan Cross <patchdev@fat-dragon.org>
