Update VERSION

Update alfred-workflow

Update get_light_gamut() to support additional bulbs

The `get_light_gamut()` function was short a few bulb models. The definition should once again be complete.

I've also updated the two developer doc links because Philips moved them without implementing a 301 redirect. This is why we can't have nice things.

Increment VERSION

Version 2.5

Fix case where nupnp returns an empty array

Group settings feedback

Referencing issue

Fixing another absolute import

Note about bugfix
