Fixed issues

• [#349] New API: Add longestName() convenience method to OptionSpec.
• [#352] New API: Add method to copy all attributes of a ParserSpec to a CommandSpec.
• [#353] New API: Add method to copy all attributes of a UsageMessageSpec to a CommandSpec.
• [#343] New API: Add method Help.Ansi.Text::concat and deprecate the append method. ("Append" suggests the Text object is modified, like StringBuilder, but Text is immutable.)

• [#344] Enhancement: Don't show WARN message for unmatched args or overwritten options.
• [#351] Documentation: Improve javadoc for OptionSpec.usageHelp and versionHelp.

Deprecations

• The Help.Ansi.Text::append method is now deprecated in favour of the new concat method.
