Dotdrop

The documentation has been moved from the readme file to [wiki](https://github.com/deadc0de6/dotdrop/wiki)

new features:

* profile `include` can now use variables (see the [doc](https://github.com/deadc0de6/dotdrop/wiki/config#include-dotfiles-from-another-profile))
* variables can be imported from an external file using `import_variables` (see the [doc](https://github.com/deadc0de6/dotdrop/wiki/templating#variables-from-file))
* `DOTDROP_CONFIG` env variable can be used to select the config file instead of `-c --cfg` (see the [doc](https://github.com/deadc0de6/dotdrop/wiki/config))
* profile dotfiles can now be imported from an external file with `import` (see the [doc](https://github.com/deadc0de6/dotdrop/wiki/config#profile-dotfiles-from-file))
* add completion scripts for bash and zsh (see the [doc](https://github.com/deadc0de6/dotdrop/tree/master/completion))
* deploy on snapcraft: <https://snapcraft.io/dotdrop>
* allow to update entire profile with `update`
