Fix Static Code Check results

... incomplete class initialization
... duplicate if statements
... typos in objects names (copy&paste) (AllPlot)
... missing else (CPPlot)
... missing DELETEs for objects (only if obvious that object is not used somewhere else)
... copy&paste errors (e.g. ModelPlot)
... small floats instead of integer evaluating to 0
... potential SEGV since pointer is not checked for NULL
... misleading code formatting (hard to read) in *zones.cpp
