Removes the old error handling library and switches to plain
fmt.Errorf calls.
There are several reasons for this:
* There are no useful types or handling here anyways, so output format
is the only priority.
* Users don't care about getting stacktraces.
* My emotional wellbeing.
Fin de siècle.
This release comes with minor usability improvements and features.
* A new 'lookupIPAddr' template function is available for resolving
DNS A records in templates. Thanks to @landro for the pull request!
* Handling of "non-standard" resource set structures has been improved
to result in better error messages and behaviour in several places.

--------------
Note: This is the last Kontemplate release that will be written in Go.
Rob Pike's art project has proven its point but I believe it is
ethically questionable and morally indefensible to continue on this
path.
You can track #72 for the Rust-rewrite of Kontemplate.
This release comes with some new features, usability improvements and
a better build & release process.
Features:
* Documentation has been improved significantly, check out the new
[README][] and follow the links within!
* Extra variables can now be loaded from files on disk. Simply specify
a list of YAML/JSON files under the 'import' key in your cluster
context file. Check out #66 for details!
* Resource set paths can now be overridden by users. By default it is
assumed that the path to a resource set is the same as its name,
however this is now user-controllable.
This means the same resource set can be included multiple times
under different names, for easier including/excluding. See #71 for
details!
* Kontemplate is currently getting a website that is under construction
at [kontemplate.works][] - feel free to check it out and
[give feedback][]!
Fixes:
* Windows release binaries now have the correct filename
* Several potential warning and error messages have been improved

This release features some cleanup and under-the-hood changes, as well
as "ecosystem-features" that don't directly affect the way Kontemplate
itself functions.
* Resource-sets are now passed on to kubectl in individual
invocations. This means that kubectl errors can be scoped to
individual resource set files and issues such as #51 are less of a
problem.
* A Dockerfile is provided and published at `tazjin:kontemplate` on
Docker Hub. This image contains `kontemplate`, `kubectl` and `pass`
and can be used - for example - as an image for a step in a CI
system.
* Kontemplate is now available on Homebrew, check the README for
installation instructions.
* If different resource sets don't contain `---` separators in YAML,
`kubectl` calls will no longer fail. (#51)
* Autocompleted trailing slashes in shells are now filtered from
include & exclude lists to enhance the CLI experience slightly.
Instead of passing the rendered output of all resource sets to kubectl
simultaneously, build upon the previous commit and pass resource sets
individually to new instances of kubectl.
This resolves#51
Replace urfave/cli with the kingpin[1] library.
It has slightly more sensible argument validation than the other Go libraries.
Additionally I've opted for removing the '-f / --file' flag in favour of positional arguments to commands.
A previous command like `kontemplate template -f somefile.yml` is now just `kontemplate template somefile.yml`. All other arguments remain the same.

* renamed --limit to --include (-i)
* added --exclude (-e)
Kontemplate users can now explicitly include and exclude certain resource sets.
Excludes always override includes.
Closes#11
* Adds support for calling `kubectl replace` (necessary for resource types that do
not support `apply`).
* Sets `kubectl` context to whatever is defined in the cluster configuration file
This integrates support for actually calling out to `kubectl apply`.
A dry-run flag is implemented, too.
The `run` command has been renamed to `template`.
Adds a basic CLI structure with a single "run" command that takes a --file (-f)
and --limit (-l) flag.
--limit can be used to only output certain resource sets.
Closes#4
