Ignore generated files by tests in extension skeleton

[rjorel]

Hi,

While testing the development of a PHP extension, I found that the .gitignore file did not make Git ignore all the files generated by the run-test.php script. I simply reported the configuration as it is in the following file without the comments :

php-src/.gitignore

Lines 223 to 250 in b976ad0

	# Generated by `./run-tests.php` upon failure
	**/tests/**/*.diff
	**/tests/**/*.out*
	**/tests/**/*.php
	**/tests/**/*.exp
	**/tests/**/*.log
	**/tests/**/*.sh
	# Generated by some test cases
	**/tests/**/*.db
	# Microsoft Access database created for passing to tests
	/ext/pdo_odbc/tests/*.mdb
	# Files generated by `./run-tests.php -m` when checking for memory leaks
	**/tests/**/*.mem
	# Test results generated by `./run-tests.php`
	php_test_results_*.txt
	# Temporary test information generated by `./run-tests.php`
	/run-test-info.php
	# Temporary POST data placeholder files generated by `./run-tests.php`
	phpt.*
	# Temporary PHP INI configuration file(s) for tests, generated by `make test`
	tmp-php.ini

Regards.
