Small documentation formatting bugs

[Remington Steed]

There are a number of small formatting bugs throughout the documentation, and it seems reasonable to group them here rather than creating separate bugs for each one. Also, I'll do my best to keep this bug limited in scope so it can be completed and closed, rather than continually adding more related bugs to this list. If you fix one on GitHub (using the "Edit" feature), simply submit it with a brief description of your changes and I should get notified. Otherwise, please comment below with a link to your code branch, patch file or Gist paste file.

Most of these files simply need a phrase to be marked in bold or italics (whatever is standard in the surrounding section). For instructions on doing this, see the AsciiDoc cheat sheet:

The Evergreen documentation style guide is also useful:

Here are the formatting bugs:
----------------------------------

https://github.com/evergreen-library-system/Evergreen/blob/master/docs/opac/my_lists.txt
Under Heading: Local Call Number in My Lists
Issue: Messy numbered list, needs two line breaks between them, rather than one.

https://github.com/evergreen-library-system/Evergreen/blob/master/docs/circulation/booking.txt
Search for text: "in I need this resource... area."
Issue: "I need this resource..." needs to be bold or italic because it refers to part of the interface. This text appears 3 times, and all of them need the same change.

https://github.com/evergreen-library-system/Evergreen/blob/master/docs/circulation/offline_mode.txt
Issue: The text "Offline Sessions" is usually bold, except for two places. Those two should also be bold.
Under Heading: Creating an Offline Session
Also under Heading: Processing the Transactions

https://github.com/evergreen-library-system/Evergreen/blob/master/docs/circulation/holds.txt
Under Heading: Alternate Hold Pick up Location -> Display
Issue: The text "Account Preferences" should be italic.
