Cornelius Weiß b7d62c7b09 initial import of my importexport work,
export is quite clean at the moment, but import needs lots of work, 

all the stuff is not really for production yet, but i import it now, so that the guy from metaways can also work on it.
most pending tasks:
- implement conversions based on regular expressions
- implement options of plugin
- rework import part (mostly ui)
