tools(templates): workflow improvments:
- template theme can be specified in parenthesis: (some_theme)path/to/template.html. Withtout parenthesis, "default" is used
- static content are supposed to be in [theme]/static, error pages in [theme]/error/[err_code].html
- default page are used in some case (2 for now): if error page with specified code doesn't exists, a base page is used, and if a page doesn't exist for a theme, the same one for default theme is looked for
- CSS files are automatically found for HTML pages
- CSS files can be split, the'll be added in the template according to the page requested.
- theme CSS file is looked for, and if not found the default theme equivalent is looked for.
- each element of a path can be associated to a CSS file, and styles.css is always there. For instance if blog/articles.html is requested, the following CSS can be included: "styles.css", "blog.css", "blog_article.css". They all must be in /static
- if the automatic finding of CSS files is not wanted, css_files arguments can be used instead, with full relative path (i.e. including theme)
- CSS files can be merged and included inline with css_inline argument
- root_path can be specified, it will be used as a prefix for static files
- requested theme (which may differ from actual theme, e.g. if the template is not found and default one is used instead) is available in template with "theme" variable
- added getThemeAndRoot method to retrieve theme and theme root path from template
