An addition to NSL helpers scripts collection to allow better integration in hypergrid environment.

For now, it allows
– integration of two currency modules, DTL/NSL and Gloebit. The structure should allow to add more.
– per domain configuration

The next step (working on it these days):
– intelligent detection of the currently visited grid, to adapt helpers as much as possible to the foreign grid

The goal is to have a complete set of scripts, compatible with most use cases.

Developed for grid, it should be fit other grids setups.
