Happy to merge with 15.05 as per #1803.

[martin.p.rowe@gmail.com: condensed InstallDev lines]

Added package nut-web-cgi based on demorfi@7e340f4794. Closes #1614.
Pending signoff by @demorfi
[martin.p.rowe@gmail.com: simplified implementation, no changes to Config.in]

Added package nut-avahi-service similar to other implementations in #618
Bugfix to remove redundant NUT_DRIVER_SERIAL config
Bugfix to make UPSLOG config actually install (requires PKG_RELEASE bump)
Some code tidy-ups
