Make all texts in the user interface translatable for translation extraction tools (such as Drupal.org localization)

Problem/Motivation

The Drupal infrastructure can extract translatable user interface strings from modules. However, the module code needs to identify these strings with a t() function. Currently not all such strings are correctly identified as translatable strings.

Proposed resolution

Render all text presented in the user interface in a translatable fashion.

Remaining tasks

1. Write a patch
2. Review
3. Commit

User interface changes

All interface text can be translated through the interface translation.

API changes

None.

Data model changes

None.

-      $message .= '<br/>Can not access your account? Use one of your recovery codes.';
+      $message .= '<br/>'.t("Can't access your account? Use one of your recovery codes.");
