Feature Request: Multiline Support

[leesoh]

It doesn't look like multiline support is currently enabled for the Grep expression. This would be a helpful feature when matching cookie directives, for example:

Set-Cookie: JSESSIONID=<blah>; Path=/reports-app; Secure; HttpOnly
Cache-Control: private,no-cache,no-store
X-UA-Compatible: IE=edge

Your regex would then look like ^Set-Cookie: JSESSIONID=[a-hA-H0-9]+; Path=\/reports-app; Secure; HttpOnly$. This doesn't currently work.

I made the following change on line 120 of IssueChecker.java locally and it worked as expected:

Matcher matcher = Pattern.compile(issue.grepExpression, Pattern.MULTILINE).matcher(strResponse);

Unfortunately, the "Use selection" feature doesn't recognize newlines, which is where I ran out of Java skills.
