CC-3611: Show Form: "Repeats" font is wrong, info images in the wrong place

Fixed both of these issues.

Fixed issue with connection URLs in "Add Show" and in "Stream Prefs" where
the text was unstyled.

Fixed issue with long connection URLS causing display problems
in "Add Show" and in "Stream Prefs".  Now a scrollbar will appear if the
connection URL is too long.

Fixed bug in Stream Prefs where zooming out caused the page to be formatted
differently.

Fixed bug in Stream Prefs where the labels "Master Source Connection URL" and
"Show Source Connection URL" wrapped on multiple lines.

Fixed help text for Add Show -> Live Stream authication settings, the
instructions were wrong and there were misspelled words.
