16b8d91baa I18N: Improve translator comments.
* Add missing translator comments.
* Fix placement of some translator comments. Translator comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools. The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translator comments.

Includes minor code layout fixes.

Polyglots, rejoice! All WordPress core files now have translator comments for all strings with placeholders!

56c162fbc9 Coding Standards: Upgrade WPCS to 1.0.0
WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.

This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script. 
- Auto-fixable coding standards issues will now cause Travis failures.

Fixes #44600.

1a28ec87e1 Docs: Remove @access notations from method DocBlocks in wp-admin/* classes.
Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

eeefec932f Administration: Improve the usage of the button CSS classes.
Introduces some consistency in the usage of the button CSS classes, fixes the
focus style for accessibility and responsiveness of the buttons.

- Adds the `button` class to all primary buttons make them responsive
- Removes all `secondary-button` classes and replaces it with button when needed. `button-secondary` shouldn't be used and exists just for backward compatibility reasons
- Replaces classes inside `submit_button()` with a shorthand for some buttons, and use an empty string for the default `button` class. Passing `button` is unnecessary
- Adjusts `get_submit_button()` to remove empty items

d27606936b Allow custom bulk actions in admin list tables.
Bulk action filtering was introduced in 3.1, but only to remove default bulk actions, not add new ones.

Bulk actions can now be registered for all admin list table dropdowns via the `bulk_actions-{get_current_screen()->id}` filter. Handling custom bulk actions can be performed in the corresponding and newly introduced `handle_bulk_actions-${get_current_screen()->id}` filter.

7a24b60c2a List Tables: to ensure that get_primary_column_name() can match columns that were added via the "manage_{$screen->id}_columns" filer, call get_column_headers() instead of $this->get_columns().
List Table classes and `WP_Screen` are already tangled together. The parent list table constructor adds a filter that is called by a function that references the instance globally, even though we have access to it via composition directly in the class that is adding the filter. So the fact that functions here have to be called that reference a screen instance we already have access to is what one might call... less than elegant.

50e42e8a07 List tables: Yet more primary column fallbacks.
Some custom list tables override enough methods for the column definition fallback to never kick in, so let's ensure that toggling columns only applies when a primary column is defined in some way. We also need to show a toggle button when we can when there are no row actions.
