[rosemacs] add xml validator for test file

[furushchev]

• add validation logic for test tag (see http://wiki.ros.org/roslaunch/XML/test)
• enable nxml-mode for extension *.test

Could you give me some more information about the *.test files? I've never seen launch files with such an extension, so I'm not sure if it's a general enough thing to be added to rosemacs.

*.test files are the test files for rostest. These are almost the same format as *.launch files, but are usually distinguished from normal *.launch file by extension. for example: https://github.com/ros/ros_comm/blob/indigo-devel/test/test_roslaunch/test/roslaunch.test https://github.com/ros/executive_smach/blob/indigo-devel/smach_ros/test/state_machine.test

Ok, let's hope that our ROS *.test files don't conflict with any other known *.test extensions.

Thanks! С наступающим.
