Description
SASEGASA ignores the FinalMaximumSelectionPressure when only a single village remains, still using the MaximumSelectionPressure and terminates too early.

I guess a plugin version increment is necessary?

yes

Surprise (or not), we will this time not increase the version number. The reasons are:
- The offspring selection genetic algorithm (OSGA) and its island version are defined in the same plugin and would also be affected by the version change. OSGA instances are used quite often in practice.
- The results of SASEGASA would not deteriorate due the change, but the runtime would increase. Results could be better though.
- Code that uses SASEGASA and stops it after a fixed amount of time would not experience worse behavior. Code that waits upon its completion however would experience different behavior. The old behavior can be restored if FinalMaximumSelectionPressure is set to the same value as MaximumSelectionPressure (which is the default).

r12886 Use the CurrentMaximumSelectionPressure instead of the MaximumSelectionPressure to determine termination.
