Started work to support older datasets

- data from 2010 and earlier is in a bit different format
- the column numbers are off by one and data is already in lat/lon
  coordinates so there is no need to convert them
- also fixed an issue where NAD83 coordinate conversions weren't getting
  rounded to two signifigant digits
Printing error message for module to STDERR instead of STDOUT!

Updated README to include instructions for bower and Linux build tips
Merge branch 'develop' of github.com:LonnyGomes/DC-Crime-Heat-Map into develop
I had foolishly rounded to just 2 signifigant digits for decimal degrees

- I was wanting to get the JSON file size down and wasn't paying
  attention
- Changed things to round 6 signifigant digits
Fixed some jslint warnings and added in 2010 to the dropdown dataset
Made the python script more versital

- it finds the proper lat/lon column indexes rather than relying on
  hardcoded column numbers
- added a try/catch to continue in case one line of data is not valid
Fixed bug where lat/lon coords were swapped for data of less than 2011
Added historical crime data up until 2006

- this appears to be the last recorded dataset available
Added basic responsivness to the menu, still needs work
Added loader bar for all of the json data
Fixed some CSS issues and added custom media queries
Adjusted header text colors and button widths in  mobile mode
Tweaked the crime year button for larger displays
Cleaned up javascript file after running jslint
Changed output folder for data to html/js/data
Removed all external dependencies -- minus the mapbox tiles

- used bower to pull in most javascript files
Tweaked heatmap display settings
Added webfonts for open sans
