Account connect w/PAC file results in multiple CriticalAlertPanels

[nrh]

Summary: on/around Frameworks/AIUtilities\ Framework/Source/AISystemNetworkDefaults.m:126, an NSRunCriticalAlertPanel is generated for every account that has 'use system-wide proxy information' checked when there is a PAC-file configured globally.

Use case:

1. User uses location switching to switch between proxy-autoconfig via file and manual proxy configuration via socks
2. User wishes Adium to use socks configuration when using socks-configured location
3. User wishes Adium to use no proxy config when using proxy-autoconfig file-configured location

In #3 above, an NSRunCriticalAlertPanel, blocking account connection, is generated for every account on every connect. This is hella annoying and the only way around it is to iterate through every account and disable the "use system-wide proxy" preference.

I suggest a better option would be to display a growl notification for the warning indicating that the system-wide PAC file can't be used. this would not block the connection from establishing and would be generally much less annoying.

(In [25577]) This might implement PAC support for proxy configuration. Fixes #224 if so. Fixes #11364 if so.

Needs testing.... I use neither a proxy nor a PAC file and can't test it. :)

nrh: Could you please try  Adium_1.4svn20081113.dmg and let us know if this fixes PAC support for you?
