Tweaktrail

To give an idea of the projects that are already registerd add an overview of a few (3 or 4?) projects to the home page for guests to visit and see what is happening.

To not get empty projects something that represents what tweaktrail can do,rules to pick projects(?):

1. at least x requests
2. at least x requests in last x time
3. interactions (votes / comments)
4. From selection pick random projects so they change when page is rerenderd.

When adding a new comment on a request it shows twice.

it should only show once, for everyone

When adding a comment to a request it says 'submit request'

alter it to 'submit comment', 'add comment' or just 'submit'

I want to be able to filter between requests on:

1. type
2. status

I also want to be able to use a search box to search for terms that might be used in an other request

In the header menuoptions you can go to releases, but you can't go back without using the browser functionality.

Add a button to go back to the 'requests' page.
