Home activity overview container

[paulotruta]

Fixing some details left after the symfony port merge for the home/index.twig.html activity overview widget:

• Handle case where there is no activity on the database yet. This will happen when the install is fresh and edgeboxctl didn't yet filled activity information in the form of Tasks. It should display a small intro message explaining what that part of the interface will contain.
• Port the widget to its own template file (that can be then easily included for easy code reutilization).

Looking at the twig documentation, two ways of doing this:

• Including a template: https://symfony.com/doc/current/templates.html#including-templates
• Emmbedding a Controller: https://symfony.com/doc/current/templates.html#embedding-controllers

Both options seem to have advantages and disadvantages. Personally I think including a template (and using pass variables to the included template) seem the simplest, most straightforward option. This will be my first attempt.

After creating a partial for the activity overview widget, got really excited about what we can reuse here!
Created an issue (#16) so we can follow up on creating partials from other elements of the interface that will or can possibly be re-used in other contexts.

Is this correct? Should we have another state for STATUS_CREATED?

This is a css color class to be applied in the template.
After testing, I noticed that the "default" class paints the icon color white, and it stays invisible.

Then I tested with "dark", which made the icon dark grey. This looked better (you could see the icon now), but the color created a mood in me which looked like the task was not executing properly or was stopped...

The "warning" class paints the icon in a shade of orange / yellow. Together with the message, it looks and feels better to have a colored icon indicating that the task is in being worked on.

Resuming, for this widget my observation of the color icons being used in conjunction with the message indicated:

Dark grey icon: Feeling of something static
Yellow icon: Feeliing of something being worked on
Green Icon: Feeling of success
Red Icon: Feeling of problem

And in the end, the created falls back to the default option of the switch statement, so it gets a yellow color.

We can introduce a case option for the created status as well, just to be more explicit (and maybe add a comment about the mood like I wrote above) :)

Added b725da3 for more clear handling of all cases.
