luci-app-*: fix all uci permissions

[PolynomialDivision]

With new openwrt versions the luci scripts that use rpcd to call uci are broken. We have to define through acl.d the permissions for each app, like I alread did in https://github.com/freifunk-berlin/firmware-packages/pull/206

• https://github.com/freifunk-berlin/firmware/issues/816
• https://github.com/freifunk/openwrt-packages/issues/23

That is for berlin firmware-packages:

• [ ] luci-app-ffwizard-berlin
• [ ] luci-app-owm
• [ ] luci-mod-freifunk-ui

openwrt-packages:

• [ ] luci-mod-freifunk
• [ ] luci-app-freifunk-diagnostics
• [ ] luci-app-freifunk-policyrouting
• [ ] luci-app-freifunk-widgets
• [ ] luci-app-meshwizard
• [ ] luci-theme-freifunk-generic

Useful to debug the apps is a code snippet:

local profile, err = uci:get("freifunk","community","name")
if profile == false then
    luci.util.perror(err)
end

Thanks for working this out.
