Add contracts and contractItems, delete old fields in character_sheet

- add contracts, but not contract bids
- Add jump fatique and etc in Phoebe. 
- Delete clone fields in Rhea.

I have troubles with XML::Simple while parsing character_sheet api response. In this Pull Request we have problem with jump_clone_implants. If we have same implants in different clones - implant merges to last jump clone in response structure. 
May be this is good time to replace XML::Simple to XML::LibXML?
