[jsword-devel] Migration to Java 5

[DM Smith]

I have just migrated our "typesafe enums" to Java 5 enums.
For an overview see: 
http://java.sun.com/j2se/1.5.0/docs/guide/language/enums.html


Basically our typesafe enums had some or all of the following features:
    Serializable
    Comparable, with deterministic ordering
    Canonical objects (hashCode, toString, equals, ...)
    a name that may differ from the spelling of the enum constant
    the ability to derive an enum from
        its name or
        the string representation of its constant name or
        the ordinal position in a global ordering
    Static state
    Dynamic global state
    Behavior

Java 5 enums has most of this. We needed to provide a lookup for its 
name and its ordinal position.

It gets rid of a bunch of code.
