Fixed NetKAN so it can now find its cache again.
Build system: Windows compatibility fixes.

We now use File::Copy::Recursive under windows to clone
our files.
Added basic tests for CKAN.Repo

This involves a change to CKAN.Repo's internals so that it can
populate a registry without needing to save it.
Fixes for error messages.

Add support for formatted error messages.
Initialize error dialog before everything else.

Hooray tests. :)

Fix for default KSP directory.
If directory not found display instance configuration dialog instead of
Exception.
Merge pull request #158 from ROMB/GUI_fixes

Gui fixes
Fixed bug where we could try to construct a Url from null.

This doesn't have a test case. I am so sorry.
Added RealChute to the Bootkan.

Tested and works! <3
Implement and test RemoveAvailable(Module module)

This is simply a shortcut to the main RemoveAvailable() that does
all the heavy lifting.

Tests included.
CmdLine: Allow installation of files from CKAN files.

`ckan install -c YourMod.ckan`

This inserts the described mod into the registry, and then installs
as per normal. If that mod was indexed from upstream, the relevant
version (and only that version) will be replaced by the one
described in the file.

This does not roll-back the meta-data insertion if the user chooses
not to install the mod. As a dev tool option, I'm not stressed by
this.

Closes #128.
