Changed the editor component from javax.swing.JTextPane to org.fife.ui.rsyntaxtextarea.TextEditorPane.
(It was too hard to implement the logic to parse the code is changed to be very random.
 But I found a bug that the editor component specified 'org.fife.ui.rsyntaxtextarea.SyntaxConstants.SYNTAX_STYLE_CLOJURE' can not
 correctly parse the next charactor literal "\(" "\[" "\{".
 So, I researched very lightly, but could not find the area to fix.
 To fix the bug, I must study about JFrex?)

Oh, One more.

Added the reader macro setting file.('src/data_readers.clj' for debug.)
