All the edits needed for the static content, and a new gitignore.

@afred, after the gitignore is merged, something like this should be done to fill in all the files. (I worried that adding them first on the live system would confuse things.) That will fix #632

```
mkdir -p public/mpot
pushd public/mpot
wget http://openvault.wgbh.org/mpot/{MPOT_Handbook.pdf,MPOT_all.zip,Original_fp7.zip,Stock_fp7.zip,Stills_fp7.zip}
popd

mkdir -p public/pdf
pushd public/pdf
wget http://openvault.wgbh.org/pdf/WGBHMLAAssessment.pdf
popd

mkdir -p public/logos
pushd public/logos

pushd public
# There are 1000s of files, so I tarred them on the OV machine. I don't have write access to web directories.
# $ ssh mccalluc@openvault.wgbh.org

scp mccalluc@openvault.wgbh.org:~/sfdb.tar.gz ~
