Changing the way you start your devserver

[ryan lerch]

Hi all,

I have this PR (that has been approved, but just not merged yet) that adds a runserver.py.

https://pagure.io/fedora-hubs/pull-request/140

Just thought i would mention it here before I merged it, as it changes the way you run hubs when hacking on hubs locally.

previously, you ran python hubs/app.py to start your dev instance, now you run python runserver.py.

This was changed because I added a few arguments for specifying the port and host, and it made more sense to not have these command-line arguments in the app.py but have a seperate spript to start the dev server.

if there are not major concerns with this, i will merge!

cheers,
ryanlerch
