Convert twikifier into a node package

A large commit that provides the following:
* Replaces Makefile with grunt for build tasks.
* twikify is run from grunt as part of the test task, it can still run standalone as before.
* The example of twikifying in the browser has gone - it's not worth the effort making this work.
 * server.js is now a node executable and packaged up into an NPM package along with twik.js and twikifier.js
 * Files have been moved into various folders to make better sense of what they are for.
 * All JavaScript apart from the TiddlyWiki stuff is linted.
 * There is now just a single script for running twikifier from /etc/init.d
Corrected single quotes typo
Corrected test tiddlers collection URI
Remove twikified Python file and update README

The twikified code has moved into it's own repository and
so it is being removed from here to keep things clean.
Service script logs to syslog and socket file in run dir

The socket file is now written to /var/run/twikifier
to be consistent with other unix processes.
This should probably be configurable when running in
 a development environment.
Make the socket file location configurable

Take the first argument to the node script as the
absolute path otherwise use the default in /var/run/twikifier
Create run dir if not present
Bump version
Merge remote-tracking branch 'upstream/master'
manual merge of changes from upstream
Merge remote-tracking branch 'origin/master' into node-package
Manual merge of upstream/master
Fixed twikify tiddler retrieval, missing pathname in path option
Remove node engine restriction

twikifier on tiddlyspace.com uses v10 now so v8 is out of date
Make sure this is executable and local modules are found

* Add a script comment stating this is a node executable.
* Use paths to find twik and twikifier relative to where server.js is running from.
Throw an exception on error so that the grunt task can fail
Don't curl during test phase
