[Htmltmpl] some improvements

[anders p. <an...@co...>]

attached is a patch for html-tmpl-1.22 python library that has a few
improvements: 

    - tags are case insensitive, so you can do <TMPL_VAR> or <tmpl_var>,
      etc.
    - it handles linebreaks within tags, so <tmpl_var
    name="foo"> is valid.
    - you can specify an include directory other than "inc" by passing
      an include_dir param to TemplateManager's constructor.
    - a set_dict() method that allows you to set multiple template
      variables at once

it still passes all the unit tests, and i've been using it on production
apps for a while now, so it should be pretty safe.
