Updated package to newest version, 3.3.0, and added ocaml.mk framework.
Changes, apart from bugfixes,
include:
  * Add `Xml_print.Utf8` to encode html elements to utf8 properly.
  * Add signature functors to ease export of module created with the functorial \ 
interface.
    See the manual for more details.
  * Fix variance for Svg.attrib.
  * Fix export of Xml.list_wrap for Html5.M and Svg.M. Should fix syntax \ 
extension with those.
  * Remove Xhtml.
  * Remove plus elements.
    For example, table doesn't enforce non-emptyness anymore.
  * Add various types that were not exported (img, dl, figure, rp, rt and ruby \ 
types).
  * Expose `string_of_number`, the better stringifier introduced in 3.1.0.
  * Functorial interface breaking changes:
    * Modify the functorized interface to export typed events.
      You can now specify different handlers for keyboard and mouse events.
      There are two new types and functions (keyboard and mous events) in the \ 
Xml signature.
    * Add a wrapping type for lists of nodes. See reactiveData and new eliom \ 
wrapping.
  * Replace fake booleans (`\`True | \`False`) by actual booleans. Breaking change.
  * Camlp4 is now an optional dependency. The syntax extension is build only \ 
when the syntax flag is enabled (true by default).
  * Use a better stringifier for float values (copied from js_of_ocaml).
  * Add attributes `muted`, `crossorigin` and `mediagroup` for `<audio>` \ 
and `<video>`.
  * In the functorial interface, allow to wrap xml nodes inside a monad by provi
ding an additionnal wrapping module. Used by reactive nodes in eliom.
  * Use oasis as build systems
  * Adding module Unsafe for inserting missing nodes or attributes
