Proxy Applet 0.2.3

Proxy Applet is a GNOME tray applet for changing your network proxy configuration with a single click, in a manner similar to Galeon 1.x.
Galeon used to have a single click Network Proxy selector in their menu, which I used frequently. In a discussion with Epiphany developers about this same functionality (using GConf) they argued that you could already move the Proxy Network capplet to your taskbar.
But that doesnt offer all the functionality Im looking for. What I think would be neat is:
- An applet that gives you a list of preset configurations upon a single click.
- Each configuration is called a location and could either mean:
No proxy
Manually configured proxy
Proxy Auto Configuration (PAC)
A remote URL, eg. http://pac.isp.net/path/file.pac
A local URI, eg. file:///home/user/pacs/location.pac
- When you select another location, the applet should replace your GConf settings accordingly. (GConf key: /system/http_proxy)
- A preferences dialog should allow to manage locations and even test a location (see if proxy works or check PAC syntax ?).
- In a later phase there might even be an automatic selection based on eg. the network-configuration (ip-address, network, gateway, ??). So the applet has to monitor the network configuration for changes.
- When using tsocks or dante lib, we could have a dialog to socksify the complete system. (Add it to /etc/ld.so.preload or run /etc/init.d/tsocks)
