Bug 1149: Fix parsing of hexadecimal w/ binary exponent floats in regexp-constant and java-parser. (Due to PCPP -> JCPP)

Lack of parsing binary exponent floats is exposed due to using JCPP
and correct constant-definitions.

- JavaParser.g:
  - Add support for hexadecimal w/ binary exponent floats
  - TAB -> 4 spaces

- ConstantDefinition.java:
  - Add RegExp 'fpRegexp', patternDecimalNumber:
      decimal number w/ support for hexadecimal w/ binary exponent floats.

  - isDecimalNumber(..): Use patternDecimalNumber
    instead of try-and-error (NumberFormatException)

  - patternCPPOperand: exclude patternDecimalNumber!

- JavaEmitter.java:
  - Respect explicit suffix [dD] for double type.
  - Drop floating point suffixes [fF]

- Test: Added tests for hexadecimal w/ binary exponent floats

- *		o  add strictfp modifier
- *      	o  missing objBlock after new expression in tree grammar
- *		o  merged local class definition alternatives, moved after declaration
- *		o  fixed problem with ClassName.super.field
- *      	o  reordered some alternatives to make things more efficient
- *		o  long and double constants were not differentiated from int/float
- *		o  whitespace rule was inefficient: matched only one char
- *		o  add an examples directory with some nasty 1.3 cases
- *		o  made Main.java use buffered IO and a Reader for Unicode support
- *		o  supports UNICODE?
- *		   Using Unicode charVocabulay makes code file big, but only
- *		   in the bitsets at the end. I need to make ANTLR generate
- *		   unicode bitsets more efficiently.
