Bug 3661 XSLT fixes

The XSLT results list (MARC21slim2OPACResults.xsl) did not have any separators between multiple 246 fields, so additional titles all ran together.  I added the standard semicolon or period as in other repeating fields.

The display for personal and corporate authors was also confusing.  The period after the last personal author (100/700) is very hard to see, so the display looked like the first corporate author only belonged to/was associated with the last personal author, rather than being a separate author entry.  I've added a dash at the beginning of any 110/710 entries to set off the corporate authors a bit in the display.

I added the same code to insert a dash before any 111/711 (Meeting author) as well.

This patch also adds missing text labels for text_list_bullets.png
(bibliography) and remote.png (available online).
