This commit adds the ability to set string, integer, and boolean values on bitmaps and profiles within Pilosa. Bitmap attributes are automatically returned when making a `Bitmap()` call. Profile attributes must be requested by setting `profile=true` in the URL. The function names have also been renamed to initial caps so that the PQL query language can support math operations in the future.
