Issue with Tomcat

[geoffroya]

With Tomcat, I can't make Bastillion work.
I found that in TemplateServlet::doGet, variable uri just equals '/'. Thus Thymeleaf fails to find the template.

This makes the trick :

       @Override
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {

		TemplateEngine engine = TemplateConfig.getTemplateEngine(request.getServletContext());
		WebContext context = new WebContext(request, response, request.getServletContext());
		context.getResponse().setContentType("text/html; charset=UTF-8");
		String uri = request.getRequestURI()
				.replaceAll("\\" + TemplateServlet.VIEW_EXT + ".*", TemplateServlet.VIEW_EXT)
				.replaceAll("^" + request.getContextPath(), "");

		if (StringUtils.equals("/", uri)) {
			uri = "/index.html";
		}

		engine.process(uri, context, response.getWriter());
	}

Any objection to a pull-request?
