Missions Offered Independend of Missions Accepted

[DocMoriarty]

Currently the number of missions offered depends on the number of free mission slots a player still has. That doesn't make too much sense and limits too much because I don't get a selection to choose from. The number of missions offered should be constantly like 5-15 missions independend from how many i can still accept, even if there is no more free slot at all because it might make me free one up to be able to accept an interesting one.
