Servlet mapping does not match base on SUFFIX style

_From [ben.andrea](https://code.google.com/u/112140932805552236028/) on February 08, 2013 13:24:00_

Description of the issue: Steps to reproduce: 1. Bind a servlet to a path with serve("/myservlet/*").with(MyServlet.class) that handles GETs.
2. Send a GET request to the server at the path /myservlet.
3. The bound servlet definition with Guice will not match the path in the request due to the way that the ServletStyleUriPatternMatcher creates its pattern.

A change like this is one possible solution:

public ServletStyleUriPatternMatcher(String pattern) {
      if (pattern.startsWith("*")) {
        this.pattern = pattern.substring(1);
        this.patternKind = Kind.PREFIX;
      } else if (pattern.endsWith("/*")) {
        this.pattern = pattern.substring(0, pattern.length() - 2);
        this.patternKind = Kind.SUFFIX;
      } else {
        this.pattern = pattern;
        this.patternKind = Kind.LITERAL;
      }
    }

The SUFFIX style will correctly match both '/myservlet' and '/myservlet/something' paths which matches the servlet specification in section SRV.11.2.
