Andrea Fercia 93dd6d907a Accessibility: Media: Make the Image Editor buttons text visible.
User interface controls that use only icons aren't ideal for many users. 

Universal icons are rare. Icons must communicate meaning but their actual meaning varies depending on many factors including the users cultural background.
Moreover, users with cognitive impairments and speech recognition users need interface controls with visible text to be able to operate them.

- shortens some of the buttons text to: Rotate left, Rotate right, Flip vertical, Flip horizontal
- moves the Undo and Redo buttons underneath the main buttons group

desrosj 894e133d0c Build/Test Tools: Introduce automated PHP compatibility checking.
This change introduces a new Composer script, `compat` that will scan the codebase for (detectable) potential PHP compatibility issues using the `PHP_CodeSniffer` and a custom ruleset based off of the `PHPCompayibilityWP` ruleset (`phpcompat.xml.dist`).

The command will be run as a separate job within each Travis build. While many compatibility issues and false positives have already been corrected in this commit and other Trac tickets, there are still some remaining. For that reason, the job is allowed to fail while the remainder of the potential compatibility issues are investigated and addressed. After those are resolved, the job should be set as required to pass to help prevent new compatibility issues from being introduced.

Props desrosj, jrf, all PHPCompatibilityWP and PHPCompatibility contributors.

Andrea Fercia 956725990f Accessibility: Make sortable meta boxes non sortable when there are no locations they can be dragged to.
Depending on the amount of meta boxes and the layout settings under Screen Options, sortable meta boxes may not be actually sortable.
In these cases, jQuery UI sortable needs to be disabled and the user interface shouldn't use a CSS `cursor: move`.

The use of consistent and relevant cursors may be important for users who have a cognitive disability, since cursors give a visual clue as to an element's functionality. Using the move cursor for elements which cannot be moved may be confusing or counter-intuitive for users.

Andrea Fercia e43633b7d0 Accessibility: Menus: Improve the menu items "Select All".
- changes "Select All" from a link to a checkbox
- the new checkbox is available only when JavaScript support is on
- semantically and for accessibility, a checkbox is a better user interface control because the available action is clear to all users and the selected state is communicated natively
- it's consistent with the existing pattern for the admin tables

Dominik Schilling 123b4475b0 Site Health: Don't verify SSL certificate when testing the local site.
The SSL certificate may be self-signed which prevents various tests from returning proper results. Since the Cron API and file editors don't verify the certificate the tests shouldn't either.

Dominik Schilling 01b6bd9f38 Site Health: Replace `wp_get_upload_dir()` with `wp_upload_dir()`.
`wp_get_upload_dir()` returns the theoretical path of the uploads directory. When there was no upload yet the test returns an incorrect result (not writeable) because the directory doesn't exist. Switching to `wp_upload_dir()`, which creates the directory on the fly, ensures a proper test result.
