Pascal Birchler aa4334cc50 Upgrade/Install: Do not remove event handlers when trying to update a theme.
Previously, when clicking "Update now" the callbacks were erroneously removed. This prevented opening the filesystem credentials modal for a second time.

Dominik Schilling aa561e67a1 Bootstrap: Enhance core's memory limit handling.
* Don't lower memory limit if the current limit is greater than `WP_MAX_MEMORY_LIMIT`.
* Set `WP_MEMORY_LIMIT` and `WP_MAX_MEMORY_LIMIT` to current limit if the `memory_limit` setting can't be changed at runtime.
* Use `wp_convert_hr_to_bytes()` when parsing the value of the `memory_limit` setting because it can be a shorthand or an integer value.
* Introduce `wp_raise_memory_limit( $context )` to raise the PHP memory limit for memory intensive processes. This DRYs up some logic and includes the existing `admin_memory_limit` and `image_memory_limit` filters. The function can also be used for custom contexts, the `{$context}_memory_limit` filter allows to customize the limit.
* Introduce `wp_is_ini_value_changeable( $setting )` to determine whether a PHP ini value is changeable at runtime.
* Remove a `function_exists( 'memory_get_usage' )` check. Since PHP 5.2.1 support for memory limit is always enabled.

Dominik Schilling bfe46464c5 Upgrade/Install: Change priority for theme/update update rows.
`wp_plugin_update_rows()` and `wp_theme_update_rows()` are using the site transients `update_plugins` and `update_themes` which are set by `wp_update_plugins()` and `wp_update_themes()`. Both functions are hooked into `load-plugins.php` and `load-themes.php`. Therefore the update rows need to be registered after the transients were populated.

Gary Pendergast 2d6b9ca91b General: Remove the `Pragma` header from responses.
`Pragma` is supposed to be a request header, but we've been including it in responses since the beginning of time.

This is a relic dating all the way back to b2, probably originally added because Internet Explorer version 5 and earlier didn't understand the `Cache-Control` header in responses, but they did (incorrectly) obey the `Pragma` header.

Internet Explorer 6 and 7 will obey the `Pragma` response header only if no other cache-related response headers are present (in our case, they are always present), and all other browsers ignore the `Pragma` response header.

Dominik Schilling 25e66e4f1e Text Changes: Unify permission error messages.
The new format looks like "Sorry, you are not allowed to <action>.". This provides a consistent experience for all error messages related to missing permissions. It also reduces the number of similar strings and allows translators to provide a consistent style in their language.

Props ramiy, Presskopp.

Dominik Schilling a288544c41 I18N: Make "That's all, stop editing! Happy blogging." translatable.
The string is used during the network installation process to inform the user about where to store additional configuration data. Since the wp-config.php file can be translated the string should be too.
