bedeviled mojo slop

Oh, and if you're running a blojsom blog and using the RSS, RSS2, or RDF flavors, you can thank Mark for all that. He gets mad props for actually putting together the Velocity and JSP templates for those flavors.

One last plug for his plug(in), blojsim - an instant messenger plugin for blojsom.

<a-team>I just love it when a plan comes together</a-team>

General:
- blojsom now requires Java 1.4.x as it now uses some of the Java 1.4 regular expression support
- Added the blojsom favicon.ico file and references in the html JSP and Velocity templates
- main.css was renamed to blojsom.css to avoid potential conflicts with existing style sheets
- dispatcher-map.properties was changed to dispatcher.properties
- Added Blog(Properties blogConfiguration) to the Blog class and removed previous Blog constructor
- Removed intermediate category output in html JSP template
- blog-file-extensions now takes a comma-separated list of regular expressions, rather than simply file extensions
- Added blog-directory-filter to blojsom.properties, which takes a comma-separated list of regular expressions for directories to filter when generating the category list
- Correctly placed requested category BlogCategory object on the context
- Powered-by logo is now href'd to http://blojsom.sf.net
- Images for RSS 0.92 and RSS 2.0 added with hrefs to the RSS feed for the current category
- Each flavor has a <link/> tag for RSS harvesters
- blojsom can now generate RSS 2 feeds. flavor=rss2

The following bugs were fixed:
BUG 689070: ClassCastException in rss.jsp
BUG 691221: All URIs need trailing /

The following RFEs were addressed:
RFE 684341: blog-file-extensions -> blog-file-name-pattern
