ARCHE-432 try to take the http session from the request since by default we have session="false" in jsp's

ARCHE-429 include %-5p (%-5p means the priority of the logging event should be left justified to a width of five characters)

ARCHE-405 remove unneeded empty hst:suffixexclusions property and the hst:prefixexclusions that only contains example values

ARCHE-403 by default give read access to all siteuser groups (sitewriters, livesuers and previewusers) for reading webresources

ARCHE-398 apply patch from Mathijs and his comment: 1. the default logger library used by Freemarker is changed from 'auto' to 'none'. This disables all logging output from the Freemarker servlet itself. Another library can be configured, if needed, via the new init param 'loggerLibrary' of the HstFreemarkerServlet.
                                                    2. the default value for the 'template_exception_handler' init param of the HstFreemarkerServlet is changed from 'debug' (the Freemarker default) to 'rethrow'. This lets the Freemarker servlet rethrow any encountered errors. The HstFreemarkerServlet then catches those errors, and only prints the Freemarker error message (and not the whole stack trace). This leads to much cleaner error message in the terminal during local development. Only when the log level of the HstFreemarkerServlet is set to 'debug' the stack traces are logged too. Note that Freemarker sometimes wraps the actual exception in a ServletException [1], so the HstFreemarkerServlet unwraps these before logging them.
                                                    3. a new logger 'warnings' has been added to the log4j-dev.xml in the archetype. This logger logs Freemarker errors to stderr with a clean log pattern (similar to the new 'messages' logger) to reduce the visual noise. Because this logger uses stderr and includes the log level 'WARN' in the output, cargo will also start the logged line with [WARNING] instead of [INFO]. This makes it much easier for developers to actually spot these warnings in their terminal.
                                                    Note that these patches make one functional change. Before, the default template_exception_handler value was 'ignore', which made Freemarker continue rendering after an error had been encountered. The new default value 'rethrow' stops rendering as soon as an error has been encountered. IMHO such 'fail-fast' behavior is better, but it is a functional change.

ARCHE-306 use session instead of request since the attr is stored on the session. Thx Bert for spotting!

Copyright statement for html5shiv was missing in LICENSE, but since IE8 support
will be dropped soon and archetypes will be replaced by Essentials archetype I
decided to remove the javascript file.

ARCHE-386: Create getting started as an integration test. Merge with other improvements from the archetype
