The tweaks PR is coming soon

[Edward K. Ream]

PR #3424 now contains the following changes:

1. The default settings in leoSettings.leo are:

@string unl-status-kind = gnx

@bool full-unl-paths = False

2. g.openUNLFile fully supports absolute paths and resolves relative paths more carefully.

3. test.leo contains tests of unls with absolute paths. Naturally, those tests will only work on my machine. They do work :-)

4. Terry's gnx, tbrown.20111010104549.26758, now identifies p.get_full_legacy_UNL. Previously it identified p.get_UNL. 

Summary

PR #3424 contains only one significant change, namely to g.openUNLFile. This PR leaves p.get_UNL unchanged.

I'll merge this PR on Monday, July 10, or before if Thomas approves.
