Add PiBorg's LEDBorg to the hardware family... (only works on Pi - and only if installed :-)
Fixed regex for LEDs to look for 0-9a-fA-F
Fix for Debug node circular references (Issue 17) - Also now limit debug message length  ...(more).    Added debugMaxLength setting to settings.js - default 512 - so can be overridden if required. (no doubt this will change)
Ad debugMaxLength to settings.js as part of Fix for Issue #17
Add notification for loss of connection to server
Open sidebar by default - fixes #18
Tweaks to Debug. realigned UI to be consistent with other nodes, Increased maxlength limit to 1000, Made circular object handling the default.
Validate functions should be called in context of the node
HTTP node not closeing properly
Add LevelDB node to the mix - a file based key value store... persistent across reboots etc.
Tweak to LEDborg to use fs.exists rather than fs.read... no need to read and catch exception
Allow nodes types to initialise asynchronously at start

The code scans the flows that are to be started and checks all
of the necessary node types are registered; if not, it doesn't
start the flows.

An event is emitted when each node type is registered - allowing
the server to track when all of the 'missing' node types register
and then start the flows.

This is a step towards adding node-types without restarting.
Much tidier Raspberry Pi GPIO node - requires @drogon 's Wiring-Pi installed... more to come
Enhance Comment block with a editbox to allow for longer comments and possible help etc
Make TCP nodes more intuitive

The edit dialog for the TCP nodes is (IMHO) clearer to use now
and provides options for how to handle the incoming messages.

The general error handling to much improved as well.
