sponsors: add & remove silver sponsors & improve script

Bountii, Earthweb and ProxyCoupons are new silver sponsors.

- The script now uses the OpenCollective username ("slug") to disambiguate
  entries when a user does not have a web site configured
- The curl invocation to download sponsors now uses more robust options
- The alt tag is now capitalized
- Perl strict mode is enabled
