patch proposal: add option to capitalize pagetitles

doc/todo/capitalize_title.mdwn

@@ -0,0 +1,31 @@
+Here I propose an option (with a [[patch]]) to capitalize the first letter (ucfirst) of default titles : filenames and urls can be lowercase but title are displayed with a capital first character (filename = "foo.mdwn", pagetitle = "Foo"). Note that \[[!meta title]] are unaffected (no automatic capitalization). Comments please :) --[[JeanPrivat]]
