Title: Add missing require

Adding a new task was failing with the following error:

```
NoMethodError at /tasks/new
undefined method `shellescape' for "test":String

file: base.rb
location: parse_params
line: 41
```

The specs are passing because the missing library _shellwords_ that defines `String#shellescape` is included by RSpec (https://github.com/rspec/rspec-core/blob/master/lib/rspec/core/configuration_options.rb#L2).

This patch ensures that _shellwords_ is included even in non-testing environment.
