LPS-43909 NTLM is not working for IE11

Hi @ipeychev, @juliocamarero,

IE11 sends this user agent:
mozilla/5.0 (windows nt 6.1; wow64; trident/7.0; rv:11.0) like gecko

So we can't use "msie" to recognise it. We have to use "trident" as the microsoft documentation says:
http://msdn.microsoft.com/en-us/library/ie/hh869301(v=vs.85).aspx
http://msdn.microsoft.com/en-us/library/ie/ms537503(v=vs.85).aspx#TriToken

Besides this pull request, I have two things to mention:
1- This is already fixed in yui:
https://github.com/yui/yui3/commit/ff025179f3b6d324af30a905cd39a8bcbb31ab0b

2- I haven't included the IE11 compatible mode in the tests since the user agent in this case:
mozilla/4.0 (compatible; msie 7.0; windows nt 6.3; trident/7.0)

it doesn't contain the version (11) so our method com.liferay.portal.servlet.BrowserSnifferImpl.parseVersion() won't be able to get the proper version. I have created another LPS to do this task (https://issues.liferay.com/browse/LPS-43946) because it's not so urgent since we don't support IE compatible modes.

Thanks.
