bookmarklet

## I will push into code here, but it's only ready when all tasks are done

steps:

- [x] the ususal wrapper (loads remote code, so it auto-"updates")
- [x] get data from current page: url, title, date(?)
- [ ] load [form](http://rss.freifunk.net/links/neu) in modal
- [ ] post(?) form on submit

possible problems: cross-domain shit (ajax, POST, …)
