Add .gitignore.
Fix JSON syntax error in default settings.

ST2 complained about this at startup. It didn't seem to bother ST3.
Remove leftover debugging print statement.
Fix #1: Python 2 (ST3) compatibility issue.

I had clearly never tested this package on ST3. The urllib.quote
function moved to urllib.request.quote in Python 3. This commit fixes it
to work in ST2 and ST3.
Prepare for 1.0.2 release.
