Labels for the different types of variables

[osemsem]

Please use the following labels, repectively:

• "Policy instruments" instead of "independent variables"
• "External factors and constraints" insstead of "uncontrollable sources"
• "Impact variables" instead of "dependent variables"
• "Policy problem" instead of "name"
• "Maximum number of iterations" should be in the same place with the time step, since we are using discrete time steps in terms of a predefined time unit, then, instead of week/month/year make the time unit here any number of weeks/months/years and all times are then expressed in this unit.

Everything is live except the max iterations. But those are updated in the unreviewed branch. I'll update the server very soon.
