Aryeh Gregor 251f4811be Cache nonexistence of grammar transformations 
Previously every call to Language::getGrammarTransformations() for a
language without grammar transformations (i.e., almost all) would look
for a transformations file using is_readable(). This is not going to be
especially expensive, but it's presumably still more expensive than
caching the result.

The change is not actually testable right now without resorting to
TestingAccessWrapper or somehow mocking the file access, but I threw in
some basic tests for the method anyway. If later we decide how best to
mock the file access, they can be updated to check that the cache is
working properly.

README 

== MediaWiki PHPUnit Tests ==

The unit and integration tests for MediaWiki are implemented using the PHPUnit testing
framework and require PHPUnit to run.


=== WARNING ===

Some of the integration tests are DESTRUCTIVE and WILL ALTER YOUR WIKI'S CONTENTS.

DO NOT RUN THESE TESTS ON A PRODUCTION SYSTEM OR ON ANY SYSTEM WHERE YOU NEED
TO RETAIN YOUR DATA.


== Installation ==

If you used composer to install MediaWiki's dependencies PHPUnit will already be available, unless
you explicitly specified the --no-dev flag during the install. In this case just run "composer update".

Otherwise follow the installation instructions in the
PHPUnit Manual at:

  https://phpunit.de/manual/current/en/installation.html


== Running tests ==

The tests are run from your operating system's command line.

Ensure that you are in the tests/phpunit directory of your MediaWiki
installation.


On Unix-like operating systems, the tests runs are controlled with a makefile.
Run command:

  make help

for a full list of options for running tests.


On Windows-family operating systems, run the 'run-tests.bat' batch file.


=== Writing tests ===
