Require all the things

[poorgeek]

Require all of the JSON spec files rather than dynamically loading them as intended.

Due to browserify/browserify#377, we have to require all of the JSON spec files and then provide an interface for only returning the ones we want from getFileSpec and getEdits.

Need to uppercase the 's' in syntactical (here and everywhere)

[poorgeek]

@doelleri I fixed the casing of the hmdaSyntactical* vars everywhere in 8b023e4. Good catch.

@poorgeek For maintainability, I would recommend this be updated with:

1. edits and specs merged into a single map called specs. Layout like:

var specs = {
        '2013': {
            'filespec': filespec2013,
            'hmda': {
                'macro': hmdaMacro2013,
                'syntactical': hmdaSyntactical2013
            },
            'lar': {
                'quality': larQuality2013,
                'syntactical': larSyntactical2013,
                'validity': larValidity2013
            },
            'ts': {
                'quality': tsQuality2013,
                'syntactical': tsSyntactical2013,
                'validity': tsValidity2013
            }
        },
        '2014': {
                   ...
        }
};

1. the vars for the file specs use filespecYYYY as the var name, not specYYYY
2. Update getFileSpec and getEdits to use the new combined specs map and variables
3. Remove VALID_YEARS
4. Update getValidYears() to iterate the top level properties of the specs map
