Contact function

Testing-Contact function for contact page is implemented, but I'm
getting Internal Server Error while trying to send an email. Have to
test it from another place or pc. It could be, that sending emails via
play framework is simply not possible.
Contact function now works

Fixed Issue with 500 server error.
- Added mail.jar to classpath - should test without on other pc
- Changed method of getting props for the mail-session.
