Manual 1.25 Archaeology Task

[fibol]

Another one for the next manual update: 5.3.6.4 Archaeology, subsection Archaeological finds, third paragraph still talks about the Archaoelogy Task of the Economic Council (which has been removed).

A different, but similar issue is that the 5th paragraph simply says that the chance to find something is a lot higher if there is an asset presetn. That is quite imprecise and vague, considering that the paragraph before that gave the exact 2.5% value for unmodified finds and feels inconsistent.
