Add action to auto build debian package

[b4ldr]

This adds an action to automatically build a debian package and add it to the release tag page every time a new tag starting v* is created. see here for an example

The action i used also parses the commits and adds them to the release to form a changelog. personally i think this is useful but im sure there will be other actions that just attach the files if its not desired.

closes #1111

thanks @b4ldr, I'll play around a bit with it on a branch
