Scala 2.10

Hi Shimi Kiviti,

Here is a pull request which simply fix deprecation errors so Cascal can be built with Scala 2.10.

This is the initial work to move it toward scala 2.10 since there are still quite a few deprecation and feature warnings.

Initial tests are fine, and I'll let you know if any errors are found.

Wish you a nice day,

Jeanluc
