Updated font-awesome CDN refs to 4.2.0, adding 40 new icons

[clojens]

As mentioned, changes to the html5 renderer to reflect latest version adding 40 new icons available to the inline icon macro. See here for an overview of how the icons look and what the names are (and consequently how they can be called from asciidoc ;)

Also updated the references in unit tests.

Hello @clojens, thanks for your contribution.
Can you please remove .un~ files ?

[mojavelinux]

Have there been any deprecations or changes in Font Awesome name mappings
we need to mention? If not, full stream ahead!

[mojavelinux]

Looks like we're good! I'll cleanup the files when I merge.

[mojavelinux]

Merged!

Thanks @clojens!

@mojavelinux sorry about the .un files, thanks for cleaning up after me. That is something new I've suddenly experienced, these files, guess resulting from tweaking vim persistent history/undo. I should probably mske vim to store those inside my ~ somewhere centrally.

[mojavelinux]

@clojens no worries.

Here's what I do to centralize my swap files in vim.

set dir=~/.vim/tmp//  " directory where the swap file is stored (trailing double slash enables full-qualified file name)
set bdir=~/.vim/tmp  " directory where the backup file is temporarily stored

[clojens]

Right so I just learned ;) Cheers.

BTW, centralized undodir is also very useful. 😸

if exists("+undofile")
  " This allows you to use undos after exiting and restarting.
  " It uses .vim-undo/ with fallback to ~/.vim/undo/ when prior doesn't exist.
  " :help undo-persistence; only present in 7.3+!
  if isdirectory($HOME . '/.vim/undo') == 0
    :silent !mkdir -p ~/.vim/undo > /dev/null 2>&1
  endif
  set undodir=./.vim-undo//
  set undodir+=~/.vim/undo//
  set undofile
endif
