More testing of the 'data' element.
ReadBinary: verify that dates, arrays, and datas are read correctly.
Various fixes to ReadBinary:

Now returns booleans the same way that the XML plist reader does.
Removed an extra round of XML entity decoding for strings that
have never been near XML. Added tests for the above.
* for version 1.38
Corrected this test for binary2.plist.
Merge branch 'merge_tests'
Add binary2.plist to MANIFEST
* for version 1.38_01
Added /Users/brian/Dev/mac-propertylist/.travis.yml
