release 0.6.12

This release includes mostly internal housekeeping. The code organization was
overhauled to better represent the division between different components.
The `cmake_format` package has been replaced by `cmakelang`, with
`format` now a subpackage. All the first class tools are now subpackages
of `cmakelang`. For now, I'll leave the github repository at `cmake_format`
but there's a good chance I'll move it to `cmakelang` in the future. Big
refactors like this have a tendency to expose gaps in coverage so please
report any breakages you observe.

In addition, the configuration now includes options for using tab characters
in listfiles (though, I'm not sure who in the right mind would choose to do
so). If enabled, the formatter will translate indentations from spaces to tabs,
and the linter will inforce a consistent tab policy.

This release also includes a couple of minor bug fixes. See the release notes
for more details.
