Enhance nm-applet icons

Better Icon set

nm-applet's standard set of icons are small which doesn't look very good on enlightenment larger shelf. There are several open source icon sets that provide better icons at a larger range of sizes.

Enhanced app-indicator support

With app-indicator unlike xembed it is not possible to overlay icons on top of each other. This means that the list of wifi networks in the menu doesn't give indication of secure vs un-secure it also means that If you have a vpn enabled you only see a padlock as indication of the vpn and not the wifi strength. To fix this I'll need to make composite icons containing both the device / wifi strength and lock indicator, i'll then need to modify the source code to use these.

qsynergy and everything else

• qsynergy's icon is also too small and doesn't scale well that should be easy to fix.
