code simplification / deduplication
* parse the string only once for a bunch of chars to check instead of starting over again and again from the beginning, created a helper function to do this (FbTk::StringUtil::findCharFromAlphabetAfterTrigger) * put same code into a function (setClockModeLabel()) * use much simpler code to switch between 12h and 24h mode and replace the fmt-switches
