There was an error in the following constants:
PREF_PROXY_AUTO_USERNAME = "proxy.manual.username"
PREF_PROXY_AUTO_PASSWORD = "proxy.manual.password"
they should be set to "auto" and not "manual":
PREF_PROXY_AUTO_USERNAME = "proxy.auto.username"
PREF_PROXY_AUTO_PASSWORD = "proxy.auto.password"
Changing the constants to the correct value now will fix the problem for
future installations of the IDE but will produce an annoying side-effect
for users upgrading from previous version of the IDE: they will lose
their saved user and pass (because it was saved as "proxy.manual.*")
and the IDE will suddenly stop working without any clear reason.
To avoid this I've left the value to "proxy.manual.*" and removed
the distinction from AUTO and MANUAL, so now we have only:
PREF_PROXY_USERNAME = "proxy.manual.username"
PREF_PROXY_PASSWORD = "proxy.manual.password"
The corresponding textbox in the preference dialog will be filled based on
the PROXY_TYPE selection.
