Move the coffeelint code out into its own function.
Init the coffeelint option once, at the top of the script. Change its
name so it begins with "syntastic_" - for namespacing purposes.
This is in response to #88 where errors like this were getting missed:
SyntaxError: In simpleMapComponent.js.coffee, Reserved word "function" on line 10

To fix this I have added another error matcher on the front of the
errorformat and have made a fix to the %-G matcher on the end (i.e. it
wasnt actually matching anything before).
The errorformat may need more updating.
