Find reason for many collation shift failures in NodeJS, ICU4J, ICU4C, etc.

The ignorePunctuation option doesn't have an effect on the test results for coll_shift_short data. This may be a problem in NodeJS

[sffc]

@sven-oly has some theories which he will post here.

[sven-oly]

Many of these failures in NodeJS and others are from:

1. Test data using rules
2. Test data with levels of sensitivity

PR #352 revises generation of collation test data, fixing many problems with rules and other test errors.

It also adds all the attributes and options from the file collationtest.txt. Note that the executors need to be updated to handle all the options now present in the test data.
