Improvements to --html5 support:

+ <nav> for TOC, <figure> for figures, type attribute in <ol>.
+ Don't add math javascript in html5.
+ Use style attributes instead of deprecated width, align.
+ html template: move <title> after <meta>.
  Note: charset needs to be declared before title.
+ slidy and s5 templates: move <title> after <meta>.
+ html template: Added link to html5 shim for IE.
+ Make --html5 have an effect only for 'html' writer (not s5, slidy, epub).
