The next commit will fix the build.
Having two commits helps keeping the history for moved files.

WIP: passing the full module to loadUnpackaged instead of only the module name
Adding a synchronous mode for the request module.

It is now possible to specify the sync option for noder-js/request,
and a synchronous request will be made. The return value will still
be a promise (not to change the signature), but it will already be
in the resolved state. Promises now have doneSync and failSync
methods which, when called on an already resolved promise, call their
callbacks synchronously.
WIP: giving access to the current context
WIP: more parameters for the NoderRequiresGenerator visitor
