Adjusted poetry indentation for Drum-Taps

Line breaks in the Drum-Taps poems were not displaying with an indent, as they did in the original volume.  I have changed the stylesheet so that line break indents are now displaying.  This also affects the display of poetry in Drum-Taps and Sequel to Drum-Taps and Complete Prose Works.

Thanks to Adam Bradford for noting this issue.

Corrections to stylesheet and transcription files for Leaves 1891-92

User Mario Corona alerted us to the absence of the bracketed note in the display of "The Rounded Catalogue Divine Complete" (Leaves 1891-92), and an investigation turned up several similar omissions, which I traced to the stylesheet. I have added a template for authorial notes in the XSLT stylesheet. I also noticed that the horizontal separators for the couple of footnotes in the 1891-92 edition were missing, so I added the appropriate code to the TEI file and created a template in the XSLT stylesheet to display them.
