Revision 665793

Some updates (improvements?) in the UAX#14-related files:
- LineBreakPairTable.txt: replace tabs with spaces to make the file a bit easier to read (constant column-width, instead of depending on an editor's settings for tabs)
- GenerateLineBreakUtils.java:
  - generate a public final utility class
  - add some spacing in the generated file, after commas and before/after '=' (same styling as manually created files)
  - use Java 1.4 String.split() to tokenize lines, instead of StringTokenizer
  - add javadoc comments for public constants and methods
- LineBreakUtils.java: regenerated after the above updates
