The RedundantStringFormatCallInspection inspection used to be able to detect excessive String.format calls and get rid of them not changing the callsite at all. This patch enhances the inspection's capabilities with changing the callsite if it is either PrintStream#print or PrintStream#println and converting it to PrintStream#printf adding "%n" if necessary.
