modified JFastReader.java

+ Made Read and Pause buttons working
+ Made Slower and Faster buttons working
+ PlayThread which automatically shows next word after specific sleep
* Bugfix with several whitespaces in a string, now whitespaces are removed using strReplace(), word-count is now correct
! Time per word is calculated using a 5-letter-word as a measure for the displayed WPM value so a 12-letter-word is displayed twice the time as a 6-letter-word. And a 3-letter-word is displayed half the time as a 6-letter-word.
! Time per word may be set to a fixed value for all words using the Options-button in the future
