Release terriamap version 0.4.4.

[na9da]

• Security fixes

  • Fixed a security bug in /proxy endpoint that allowed requests to a variation of domains in the allowProxyFor list. If example.com is in allowProxyFor setting, this allowed requests to a domain with a different prefix, like badexample.com to pass through. #212

• Deprecations

  • Deprecates most of the proxy domains in the default serverconfig.json file. These will be removed in a future release, so please add them through a custom serverconfig.json if you rely on terria proxying to any of these servers.
