Currently the client will just send the request and the player will
get the feedback because either something changes or an error message
occur or nothing changes at all.

If the client want to simulate a certain situation it has currently
two options:
 - make a request to the server and wait for the response (which maybe
 will come never). Some actions can be reverted (worker assignment)
 some can't (unit movement).

 - use code from common to perform the same calculations like the
 server. The client may not know everything the server may know. But
 knowledge for example is sufficient for example to accurately
 simulate the production of a city. After the simulation the client
 sends its selected action to the server.
