Update hubble.coffee

Get a case sensitive file system :-P
Merge pull request #3 from datamuc/patch-1

Update hubble.coffee (case-sensitive issues)
now supports polling
updates to readme
didn't have request in package.json so the app was throwing an error on launch
Refactoring for a more command line feeling usage
Config is now pulled from current directory. This should allow an NPM deploy
simplified install with npm (thanks Charles) and updated readme
polling now also supports getting a json value from a response (see readme)
I have OCD, so i'm redoing my screenshots to all have the same shade of black since I changed my terminal. Also, a github value (last commit) was missing and I needed to add it
now supports adding blanklines and single-text lines (like section headers)
verifying a polled value isn't a number so it doesn't get momentified
refactored to only use one getInCenter method
bumped version
fixed issue where the line size didn't always fit perfectly in the console, so it would wrap or be too short
Added a feature that allows for incrementing of values (specify value=increment)
added value=increment feature for incrementing previously set values (Thanks Andy!)
now supports multiple screens
board draws after polling if it is the active board
finished 'screen' feature, bumped version and updated readme
