Update Nimrod to 0.10.0

Update **Nimrod**, **Jester** and **Nawak** to their latest versions.
- Nawak incorporated its stdlib changes upstream, and is now using and dependent on the nimble package manager and the nim-zmq and nim-uuid package. It was also made compatible with the latest Nim/Nimrod.
- Jester is using its new async (unfortunately there is no scgi support for now).

N.B.: Nimrod the programming language is being renamed Nim when the official 0.10 comes out.
I don't even think they are up to date with the directories change (when everything was put into `frameworks/languageX/...`.
Should this be a path relative to TROOT, or FWROOT? Right now, they are all broken, because they refer to the old FWROOT.
