Allow tasks to inherit inline-tags

Just like an indented bullet point will inherit the inline-tag that is placed on a bullet point above it, allow a task to do the same.

- New Coffee Maker Project @personal
Description of the coffee maker project with any thoughts about it.
- task: buy the good beans
- task: @research best espresso maker

In this example, all the tasks would inherit the @personal tag and the research taask would also be labeled as @research
