Sync module authentication issue with "&" symbol in password

[knightphoenix]

If your password contains the "&" symbol it seems you cannot authenticate using the sync module

Logon to both emoncms.org and the local system will work as expected but attempting to authenticate to the sync module will cause a generic authentication error to appear and you will not be able to proceed (the api key wil not show and you cannot download or upload any inputs or feeds.
