[Feature] Show addon changelog

[ckaotik]

A revived Minion, finally! I'd love to get rid of Curse's stupid antique alpha thingy and besides WoW support (which was talked about in other treads already) there is pretty much only one feature I really miss:

The ability to easily check an addon's changelog. When I see the "Update" button in my addon list, I always have to find the "visit Website" link and navigate to the "Changes" tab. It would be great if those were also included in the Minion itself without having to launch the browser
