Updated the README and zip files to reflect the new version that includes CybOX output.
1. Command-click now clears a tag in Mac OS. Right-click had unexpected effects. 2. Loading a file drops all carriage return characters because they display incorrectly in Mac OS and Ubuntu. 3. Letters in MD5 hashes are always treated as capital letters to avoid two hashes being considered different based only on capitalization. 4. The IPv4 regular expression now matches an IP followed by a number (this appears when an IP followed by a footnote is saved as plain text). 5. Manual tagging deletes a newline character inside the selection to allow tagging IOCs split across lines.
