Add command to add tasks to different backlogs via input box

[mihaiconstantin]

Description

1. The user runs BuJo: Capture Task.
2. An input box opens and the users type the content of the task.
3. A quick select view opens with all backlogs pro-populated (i.e., either from a user setting or via a regex pattern based on the files in the repository). Here the user selects with the arrows which backlog to add the task to and presses enter.
4. A confirmation box is shown that the task has been added to the corresponding backlog.

Configuration Properties

• bujo.captor.backlogList: the backlogs to show in the quick select box. If null, then the backlogs will be pre-populated based on regex.
• bujo.captor.showBacklog: whether to open or not the document where the task has been added.
