Patch ImageJMacroTokenMaker to accommodate RSyntaxtTextArea v3.6.0

This fixes the issue detailed in scijava/pom-scijava#288

Context:
In newer versions of RSyntaxtTextArea, AbstractJFlexCTokenMaker adds an abstract yystate() method intended to return the current state of a JFlex lexer.
Since it is abstract, it must be implemented by any concrete subclass, so we patch ImageJMacroTokenMaker so that the current zzLexicalState is returned

Tested with: `mvn clean package -Denforcer.skip`
