Add support for following wiki links in a buffer

This patch adds support for automatically following wiki links in a
buffer. If you are on a link and you hit the enter key or \C-c\C-f the
document pointed to by the wiki link will be opened in another buffer.

This functionality was originially in wiki mode by Alex Schroeder
<alex@gnu.org>. It has been heavily modified and moved here by the
patch author.
Silence byte compiler warnings in GNU Emacs 23.

Also markdown-check-refs now starts on the first missing reference
instead of the second. Seems like a more natural starting point.

highlight wiki links differently based on backing file existance

This patch tries to make it obvious if the file that a wiki link
points to exists or not. So it highlights wiki links that do exist
differently from those that do not.
Fix wiki link navigation

Use markdown-wiki-link-p instead of nonexistent markdown-wiki-name-p.
Update docstrings to pass checkdoc

Short first line, complete sentences, mention all arguments in uppercase, etc.
Use built-in font-lock-warning-face for missing wiki links
Avoid using deprecated function make-local-hook

make-local-hook was removed from Emacs 24.  We now check for

add-hook is an optional LOCAL argument, which we set to t.
