[Jesper Öqvist]

Improved option parsing and handling

• Improved Option API by removing boolean traps in constructors
• Do not let accepted values collection be null!
• Represent indentation using number of spaces rather than String object
• Removed CommandLineArguments class - replaced by ArgumentParser
• ArgumentParser has list of filenames rather than operands
• ArgumentParser works with prefix map to speed up option matching
• Renamed JastAddConfiguration to Configuration
• Added subclass ValueOption of Option
  • Option now only handles options without values
  • ValueOption handles options with values
• Added anonymous classes for each option that handle option matching
• Added package org.jastadd.option for option handling classes
• Simplified option matching - all work is now done in ArgumentParser
• Print warning when non-accepted option value is encountered
• Improved cache option checking
