opennds: Create new Package, release v5.0.0

Maintainer: Rob White <rob@blue-wave.net>

Compiled and tested on snapshot SDK for mipsel_24kc, mips_24kc and arm_cortex-a7_neon-vfpv4

This is the first release from the OpenNDS project.

The decision has been made by the developers of the NoDogSplash project, to create a new project, beginning at v5.0.0

The two resulting projects are:

 * **OpenNDS**, the new project, optimised for development of custom captive portal solutions using the built in Forwarding authentication Services API and associated libraries.

 * **NoDogSplash**, the original project, optimised for hardware with very restricted resources (eg legacy 8/32 devices) and supporting only simple templated splash pages.

At v5.0.0 of both projects share a common code base.

However, the two packages will inevitably and rapidly diverge, as OpenNDS is actively developing, whereas NoDogSplash is feature complete for its optimised target use.
