New version highlights

From the release notes:
Version 1.1
General:
- added jetty servlet engine and to automate the tests. The tests can now be run by using ant run-tests

springworkflow:
- added default behaviour in the creation of actions, meaning when you create an action tag with display="button" the onClick event will generate a submit of the form, whereas when you use a action tag with display="link" an a href tag will be created where all of the parameters needed for the workflow will be included. Please note that this means that all other parameters of the form will not be submitted. The link is now a real link again meaning you can bookmark it. If however, you want to display an action as a link but still have the form submit all of its parameters, you can set the linktype parameter of the action tag. If you set the linktype="submit" then all of the parameters will be submitted by calling the javascript:go function. If you set the linktype="href" then a link with workflow parameters will be generated.
- added a type="back". If you set an action tag with type="back" then the resulting action will go back to the previous page the user was one. This is the same as the browser back button but the server now knows of it, and thus appropiate action classes could be called. This option is usefull when you have a page that can be accessed from many other pages, but should always go back to the page that the request originated from (e.g. on each page there is a link with "change account". On this page you can update your account information and by pressing the back action, the system will return the user to his/her previous page where the newly changed information will be visible. This is different from the browser back button, because the server would not receive a new request for the previous page, and thus the previous account information would still be visible.

rssreader:
- added categories. For now there is a view with categorized channels where only the categorized channels are visible at the moment. Next phase will add categorized items and update the search engine to search only for categorized items.
- added a special action in the admin section to poll redirected channels. The httpClient did return a error when a blog was moved, but the system didnt follow up on this code. This is changed now, however the blogs that arent polled anymore because the pollsStarted index has exceeded 10 will never be polled again. With this option, all those blogs will be polled again.
- bug solved. When deleting an item, the searchIndex would be deleted as well.
