v2.1.12 - Windows Spaced Path Fix

Fixes

• Windows paths with spaces in them now work with eslint-watch ( #86, #84 )

Misc

• Watch directory is now specified as ./ if one isn't specified
• Appveyor is back (bad idea to remove it)
• ESLint is now being executed via spawn rather than exec. Also making it easier to execute a command and parse the whole result via src/executer.js
