Add option to pass custom date and time formats

[gazayas]

This gives developers the option to pass a custom format to Date and DateTime partials.

Given a model named PartialTest with a Date attribute named date_test, we can write the following:

<td><%= render 'shared/attributes/date', attribute: :date_test, url: [:account, partial_test], date_format: "%m/%d" %></td>
<td><%= render 'shared/attributes/date_and_time', attribute: :created_at, date_format: "%m/%d", time_format: "%I %p" %></td>

This gives developers the freedom to write their own formats if they want to.

Setup

I'm having a problem with the test because Capybara isn't picking up on the changes made when overwriting the file. I'm not quite sure how to handle this one, but I thought it would be better to push some tests rather than none.

Also, we need the chronic gem which is to be pulled in via this PR. Before that gets merged in, you can check the logic by replacing the appropriate Bullet Train packages in the Gemfile, along with simply adding Chronic:

gem "chronic"
gem "bullet_train", git: "[email protected]:gazayas/bullet_train.git", branch: "features/custom-date-formats"
gem "bullet_train-themes", git: "[email protected]:bullet-train-co/bullet_train-themes.git", branch: "features/custom-date-formats"

Joint PR ← Bullet Train Base
Joint PR ← Bullet Train Themes

@gazayas This looks good to me, and since the dependent PRs are already merged it seems like it should be good to go. Except for the fact that there's a merge conflict. If we can get the conflict sorted out I think we should merge this.

@jagthedrummer I ended up removing the tests for the custom formats because Capybara wasn't picking up on the edited page. I originally was working with _index/html.erb but changed it to show.html.erb. Here's how I edited the file:

transformed_content = original_content.map do |line|
  if line.match?(/attribute: :date_test/)
    line.gsub(/ %>/, ", date_format: #{custom_date_format} %>")
  elsif line.match?(/attribute: :date_time_test/)
    line.gsub(/ %>/, ", date_format: #{custom_date_format}, time_format: #{custom_time_format} %>")
  else
    line
  end
end

After editing the file, running refresh to refresh the session and then visiting the show page, the changes weren't present in the test although it was working fine in the browser.

What I can do is write about the change in the docs, we just won't have tests for now.

Now we just have 0 changes though, also because we added PartialTest in another PR after I opened this one... I'll write up some documentation and link it here, then close it.

Just opened bullet-train-co/bullet_train-core#364, will go ahead and close this one.
