First pass at commas to semicolons

I'm getting some bad data in the PostGIS database because of the quoted
fields where commas are used within a delimited field. So I'm switching
these non-delimiting commas to semi-colons. This is the first pass
before taking another loop with the regex to get the 2nd set of commas
within the delimited fields.
Finishing comma to semicolon fix

Using semicolons to in place of commas within the delimited
data fields. This fixes some problems with using the csv
files as imports for the PostGIS database
Merge branch 'semicolons' into reorg

Used a different method to fix the commas, so I had to skip back a commit. Merging here to get the latest correct data
