Removed deprecated fancybox init

Lightbox for a.InputfieldFileLink is already defined at
InputfieldImage.js so do we even need to repeat it here? Seems to work
just fine without. See:
https://github.com/ryancramerdesign/ProcessWire/blob/master/wire/modules
/Inputfield/InputfieldImage/InputfieldImage.js#L20
Added InputfieldFileData class to crops div

This hides crops div when image is merged for deletion. See:
https://github.com/ryancramerdesign/ProcessWire/blob/master/wire/modules
/Inputfield/InputfieldFile/InputfieldFile.js#L41
Added support for grid view (fixes #20)

Class InputfieldImage is required for grid view. See:
https://github.com/ryancramerdesign/ProcessWire/blob/master/wire/modules
/Inputfield/InputfieldImage/InputfieldImage.js#L59
