Default avatars and icons becomes invalid in light build

[OmarElawady]

The --light build option is used to build only the English language to speed up the process. But it seems that all icons and avatars become invalid. However, normal installation without this flag works as expected.

Note: It tries to access /client/stuff/avatar.png but the resource is found in client/en-US/stuff/avatar.png . So either it should be linked or the default client path should be changed.
