Allow regex patterns for @expectedExceptionMessage

[marcioAlmada]

I noticed some "pain" around this subject for a good amount of people so decided to propose to allow regex patterns for @expectedExceptionMessage.

This feature could keep test suites dryer when dealing with fuzzy exception messages while keeping consistency when test annotations are preferred. Ex:

/**
 * @expectedException ParserException
 * @expectedExceptionMessage /Cannot use \w+ as type \w+ (on line \d+)/
 * @dataProvider typeErrorProvider
 */
   public function testTypeError()
   { ...

Some dynamic exception messages that would pass the example test:

• Cannot use 2 as type float (on line 2)
• Cannot use sebastian as type integer (on line 14)

PS: I could create a pull request if you think it's worth it.
