run-tests.sh ignores classes if they have whitespace before the declaration using --directory

Problem/Motivation

run-tests.sh ignores classes if they have whitespace before the declaration using --directory

So if you have something like

namespace MyNamespace {
   class WhateverTest {
   }
}

the test is not run. But works if you have

namespace MyNamespace {
class WhateverTest {
}
}

Proposed resolution

Change the regexp for namespace and class declarations to include \s*

Remaining tasks
