Merge branch 'master' of git://github.com/jquery/jquery

Added support for .text() on text nodes. Fixes #5525.

Re-wrote context Ajax test to use an element instead of an object (a more realistic test and works with the new jQuery.extend logic for cloning object literals).

Re-adding the QUnit submodule file.

Changed the === undefined ready event check to == null since frameElement is usually null and was skipping the normal line of checks.

Hide the .settings file in the gitignore.

Ignoring src/selector.js (build) and Emacs backup files

Merge branch 'master' of git://github.com/jquery/jquery

Added test for passing null to .show()

Allowing falsy values to be passed as a speed for hide().

Allowing falsy values to be passed as a speed for show().

Corrected some minor errors made by me (rkatic) in last commits.

Forgotten to update the number of jQuery.extend related tests.

Made jQuery.extend(true, ...) to extend recursively only 'object literal' values.

Made isObjectLiteral to work correctly with custom objects with empty prototypes.
