Simple CLI client for `trello.com`. It can be used like this:

```
$ export TRELLO_USER=your_username
$ export TRELLO_KEY=your_key
$ export TRELLO_TOKEN=your_token
$ ./result/bin/3llo
```

I didn't create a module for this as I don't think that those secrets
should live in the Nix store. Ideally `3llo` can be used from a script
which retrieves secrets from some kind of password store like this:

```
export TRELLO_KEY=$(pass show trello/key)
export TRELLO_TOKEN=$(pass show trello/token)
3llo $@
```

The `gemset` field can be an attribute set as well in `buildRubyGem`,
however attribute sets can't be coerced to strings for the environment
set.

The impact should be relatively small as the environment variables are
only used by the `runCommand` script for `bunlderApp` which doesn't
refer to `gemset` at all.

This should also ensure that the applications get wrapped
appropriately.

LXQt uses the values in this macro to set installation
directories and in the case of lxqt-session to substitute in paths.
However, by doing this all the paths are from within lxqt-build-tools
prefix. By utilizing a setup hook we can set the directories with the
correct prefix as cmake flags.

See https://lists.gnu.org/archive/html/info-gnu/2019-08/msg00006.html
for release information.

Seems to break systems using the hardened profile.
