Enable VisualStudio style by default

This tweaks `CKAN.sln` so that it uses VisualStudio layout by default.
At some point it lost this and went back to wanting to use tabs and
other oddities.

`CKAN.sln` is black magic to me. I'd love to find another way for
MonoDevelop to determine text formatting settings.
Add .ackrc file for better searching.

This adds an `.ackrc` file, for use with ack ( http://beyondgrep.com/ ),
a rather awesome text/code searching tool. For people who aren't using
ack, it won't do anything or cause any harm. :)
