Add appropriate changes to be able to target Grimoire
A little more tweaking on arrdem's Grimoire link targets

Make the Vars added to Clojure after Clojure 1.3 point to Grimoire,
too.

Fix a few other links, but there are still some links to Grimoire that
are broken, particularly for special forms.  Might fix those later.
Update list of vars not on the cheatsheet
Eliminate most use of dynamic vars in favor of additional keys in map 'fmt'

Also add a few unit tests for a function I want to add new options to
soon, to help verify I don't break anything.
Change what was unnecessarily a ref to an atom
Minor code cleanup
Rework fn table-cmds-to-str for better clarity
Add option to expand out the common prefixes/suffixes

Expanding them out makes those symbols searchable by their original
names, at the cost of making the cheatsheet have a bit more text.
Make it the default to expand common prefixes and suffixes
v15 of the cheatsheet, with no more compressed abbrevations

and replacing unchecked-*-int operations with their long versions,
where they exist.
Generated HTML and PDF files for cheat sheet v15
Make the search box match literally chars that are special in regexes

Before this change, searching for ? or * would treat those characters
as having their special meaning inside JavaScript regexes.
Leave search box unhighlighted when it is empty or contains only whitespace

Technically, it doesn't match anything then, either, but people seem
to prefer it being red only when they have typed something that has no
matches.
Some keyboard usability improvements

* Escape-hatch in input event handling for ' and /, the firefox
  find as you type shortcuts
* Bind 'escape' to searchbox focus, vim-style
