First pass at cleanup and geocoding.

Standardized street names and sorted street abbreviation lookup;
Added zone number to zone tab as a column;
Moved notes to notes tab;
Duplicated missing column data so rows are complete;
Fixed some misspellings;
Fixed some missing row data;
Add geocode addresses and lat/lon;
Removed unfilled category column;

Notes:
Some addresses don't have geocode data and refer to a single point.  (see Powning Park)
Some streets don't have equivalent abbreviations and are marked as "?".  The ones affected don't seem to have any revenue data.
From and To column street names are not standardized, but are duplicated so all rows have the data.
No lookup for Hours column, so not sure how useful that is.
